Abstract:

ÖZ Grafen ilk izolasyonunun gerçekleştirildiği 2004 yılından beri iki-boyutlu nano materyaller arasında bir yıldız olarak araştırmacıların dikkatini çekmektedir. Özellikle yeni keşfedilen 2D boyutlu materyal ailesi boyutsallıklarına bağlı olarak esneklik özelliğinin oluşumuna olanak sağlamaktadır. Bilinen ilk iki-boyutlu nano materyal olan grafenin sahip olduğu mükemmel termal, elektronik, optik ve mekaniksel özelliklerinin zenginliğinin yanı sıra, eşsiz 2D yapısından dolayı esnek optoelektronik aygıt uygulamalarında sıklıkla tercih edilmektedir. Bu sayede insan arayüzlü cihazlar, robotik cilt, giyilebilir optoelektronik cihazlar, dokunmatik ekranlar, ultra hızı lazerler ve ışık yayan aygıtlar gibi esnek ya da gerilebilir cihazlara duyulan büyük ilginin oluşmasına ve bu alanda yürütülen çalışmaların hız kazanmasına sebep olmaktadır. Bu incelemede, grafen tabanlı optoelektronik aygıtların geliştirilmesindeki son gelişmelere kapsamlı bir genel bakış açısı sunmanın yanı sıra bu alana ilişkin gelecek perspektifleri de tartışılmaktadır.

Abstract:

Bu çalışmada, esas olarak mikrodenetleyici tabanlı çok kanallı ve kanal genişliği ayarlanabilen bir dijital geçikmeli darbe üreteci (DGDÜ) tasarımı gerçekleştirilmiştir. Bu sistemde mikrodenetleyici (PIC18F4550), kristal osilatör (8 MHz) ve 4 giriş 16 çıkışlı kodlayıcı/kodçözücü entegresi (74LS154) kullanarak 1µs-1s arasında 25 farklı genişlikte zaman-taban sinyalleri üretilmiştir. Tetikleme sinyalinden sonra seçilen zaman-taban genişliğinde ardışık olarak 32 kanallı zaman-geçiktirme dijital darbe sinyalleri elde edilmiştir. DGDÜ sistemi, ilk olarak genlik-zaman bağımlılığı bilinen referans üçgensel sinyalin bir tam periyodu içinde seçilen iki zaman pencere değerine karşı gelen sinyal genlik değerlerinin 2-kanallı örnekle-tut devresinin de bulunduğu Sinyal Analiz Birimi (SAB) ile test edilmiştir. Elde edilen sonuçların bilinen gerçek değerler ile karşılaştırılması yapılmıştır. Sonuçların uyumlu olduğu gözlenmiştir. Daha sonra ticari bir ürün olan ve ışığa duyarlı bir direnç (LDR) için oda sıcaklığında, kesikli aydınlatma ile oluşan foto-akımın zamanla matematiksel formunun belirlenmesi için kullanılmıştır. Sonuç olarak, bu yeni mikrodenetleyici tabanlı çok kanallı DGDÜ ve SAB ile hızlı, işlevsel ve esnek özellikleri olan bir otomatik veri toplama sistemi gerçekleştirilmiştir. Ayrıca derin seviyeli transient spektroskopi (DLTS), foto-uyarımlı akım transiyent spektroskopisi (PICTS) gibi yarıiletken mazlemelerin karakterizasyonları için kullanımı kolay ve ticari çift-örnekleme sistemlerine göre daha ucuz olması nedeniyle tercih edilebilir bir sistemdir.

Abstract:

GaN merupakan material semikonduktor yang memiliki nilai celah pita energi (Eg ) sekitar 3,45 eV pada temperatur ruang dengan struktur transisi langsung. Keadaan ini membuat GaN sangat potensial untuk aplikasi divais optoelektronik yang beroperasi para rentang panjang gelombang UV. Dalam studi ini telah dilakukan uji penumbuhan lapisan (GaN) di atas substrat Si (100) dan Al2O3 (0001) dengan teknik sol-gel spin-coating dengan menggunakan kristal gallium-citrate-amine sebagai prekursor Ga. Teknik ini tergolong sederhana, mudah pengoperasiannya dan relative murah. Hasil karakterisasi lapisan GaN yang berhasil ditumbuhkan menunjukkan bahwa baik yang ditumbuhkan di atas substrat Si (100) maupun Al2O3 (0001) masih memiliki struktur polikristal. Kualitas morfologi lapisan GaN masih relatif rendah, dengan ketebalan rata-rata berkisar antara 1-1,5 m. Nilai celah pita energi lapisan GaN yang ditumbuhkan di atas Al2O3 (0001) berdasarkan hasil karakterisasi UV-Vis spectroscopy adalah sekitar 3.20 eV. Nilai ini masih sedikit lebih rendah dari nilai idealnya.

Abstract:

AbstrakReduced graphene oxide (rGO) merupakan salah satu nanomaterial dengan diameter ukuran partikel dalam skala nano yang memiliki sifat mekanik, optoelektronik, atau konduktivitas yang menyerupai seperti graphene. Hal ini dikarenakan rGO memiliki struktur heterogen yang terdiri dari bidang dasar seperti graphene yang memiliki cacat struktural karena penyisipan oksida ke dalam strukturnya. Material rGO banyak digunakan karena metode sintesisnya lebih mudah jika dibandingkan dengan sintesis graphene, namun rGO mempunyai struktur dan sifat yang menyerupai bahkan lebih baik jika dibandingkan graphene. Metode sintesis untuk memproduksi rGO adalah pengelupasan mikromekanik dari kristal grafit, penumbuhan epitaksial, chemical vapor deposition (CVD) dan sintesis kimiawi dengan cara mengoksidasi grafit. Dari hasil sintesis rGO memiliki sifat yang unggul yaitu konduktivitas listrik yang baik, luas permukaan yang besar, stabilitas kimia yang baik, dan rapat daya yang tinggi. Namun terdapat masalah dalam rGO sebelum di modifikasi dengan bahan lain, yaitu memiliki dispersibilitas rendah pada pelarut organik dan anorganik biasa. Maka dari itu artikel ini membahas mengenai pengembangan terbaru struktur, sifat dan kinerja dari rGO dan kompositnya yang disusun berdasarkan review dari berbagai artikel, sehingga dapat memperluas aplikasinya seperti baterai, superkapasitor, katalis, optoelektronik, bahan anti korosi, dan membran.Kata Kunci: reduced graphene oxide, graphene, komposit AbstractReduced graphene oxide (rGO) is a nanomaterial with a diameter of particle size in the nanoscale that has the same mechanical, optoelectronic, or conductive properties as graphene. This is because rGO has a heterogeneous structure consisting of a basic plane such as graphene which has a structural defect due to the insertion of oxide into its structure. rGO material is widely used because the synthesis method is easier when compared to graphene synthesis, but rGO has a structure and properties that resemble compared to graphene. Synthesis methods for producing rGO are micromechanical peels from graphite crystals, epithaxial growth, chemical vapor deposition (CVD) and chemical synthesis by oxidizing graphite. From the results of the synthesis of rGO has superior properties namely good electrical conductivity, large surface area, good chemical stability, and high power density. However, there are problems in rGO before being modified with other materials, which have low dispersibility in ordinary organic and inorganic solvents. Therefore this article discusses the latest development of the structure, properties and performance of rGO and its composites based on a review of various articles, so that it can expand its applications such as batteries, supercapacitors, catalysts, optoelectronics, anti-corrosion materials, and membranes.Keywords: reduced graphene oxide, graphene, composite

Abstract:

Quantum Dot adalah bahan nanokristal semikonduktor yang sangat kecil sehingga menyebabkan energi gapnya merupakan fungsi dari ukuran partikel, semakin kecil ukuran partikel menghasilkan energi gap yang semakin besar. Salah satu jenis bahan Quantum Dot adalah amorphous Silicon Quantum Dot (a-SiQD) yang memiliki potensi besar untuk bahan teknologi optoelektronik dan telah dikembangkan secara eksperimen nanostruktur a-SiQD untuk mempelajari efek quantum confinement dan karakteristik emisi cahaya. Pada penelitian ini, dibuat model klaster a-SiQD dengan melakukan teknik translasi untuk memperbesar ukuran dan membuat klaster berbentuk bulat dengan menghapus beberapa atom silikon terluar dan menambahan aton hidrogen. Untuk mendapatkan karakteristik elektronik dan optik klaster a-SiQD, dilakukan perhitungan energi gap menggunakan metode Extended Hückel Theory (EHT). Hasilnya, ketika variasi dot size klaster a-SiQD mengalami penurunan dari 2,1 nm ke 0,85 nm energi gap mengalami peningkatan dari 2,29 – 4,53 eV. Tidak hanya itu, bentuk bulat dan penambahan atom hidrogen juga mempengaruhi besar energi gap klaster a-SiQD. Sehingga rekayasa energi gap klaster a-SiQD dapat tingkatkan dengan mengatur dot size, bentuk dan jumlah atom hidrogen.

Abstract:

Piranti-piranti elektronik maupun optoelektronik yang efisien dan responsif saat ini tengah masif dikembangkan dalam beragam bentuk dan jenis. Meta-material merupakan rancangan optoelektronik yang unik dengan sifat elektromagnetik yang tidak ditemukan secara alami, salah satunya adalah peristiwa indeks bias negatif. Eksplorasi terhadap banyak ragam struktur metamaterial sangat penting dilakukan untuk mengidentifikasi karakteristik tiap struktur. Salah satu struktur metamaterial yang menarik dikaji adalah bentuk heksagonal. Penelitian ini menginvestigasi karakteristik frekuensi resonan dan distribusi medan elektromagnetik metamaterial split ring resonator heksagonal (SRR-H) yang dikombinasikan dengan stripe line (SL) berupa logam tembaga. Lebih lanjut, jumlah SL divariasikan dari 0 - 5 unit dan disimulasikan dalam medium udara dalam rentang frekuensi 1 – 7,5 GHz. Hasil simulasi menunjukan adanya pergeseran frekuensi resonan untuk tiap penambahan SL dalam rentang frekuensi 4,31 – 5,82 GHz. Sebaran medan listrik cenderung terpusat pada cincin resonator sedangkan medan magnet cenderung terdistribusi pada SL. Desain metamaterial SRR-H dengan 3 SL memberikan respon disipasi energi yang terkecil dengan medan E maksimum 2,59 kV×m-1 dan medan H maksimum 8,69 A×m-1. Desain SRR-H ini cukup potensial untuk diaplikasikan sebagai antena gelombang elektomagnetik yang efisien dan juga sebagai biosensor. Efficient and responsive electronic and optoelectronic devices are currently being massively developed in various forms and types. Metamaterial is a unique optoelectronic design with electromagnetic properties that are not found naturally, one of its properties is a negative refractive index. Exploration of different types of metamaterial structures is very important to identify the characteristics of each structure. One of the interesting metamaterial structures is a hexagonal shape. This research investigates the resonant frequency characteristics and electromagnetic field distribution of split-ring resonator (SRR-H) hexagonal-shaped metamaterial which is combined with the copper stripe line (SL). Furthermore, the number of SL is varied from 0 to 5 units and simulated in the air medium in frequency range of 1 - 7.5 GHz. The simulation results show a resonant frequency shift occurred for each SL combination in the 4.31 - 5.82 GHz frequency range. The distribution of the electric field tends to be concentrated on the resonator while the magnetic field tends to be distributed on the SL. The SRR-H metamaterial with 3 SL provides the smallest energy dissipation response with a maximum E field of 2.59 kV×m-1 and a maximum H field of 8.69 A×m-1. The SRR-H design is potential enough to be applied as an efficient electromagnetic wave antenna and also as a biosensor.Keywords: Metamaterials, SRR-H, strip line, resonant frequency, electromagnetic field

Abstract:

Material perovskite menarik perhatian peneliti dibidang fotovoltaik karena fabrikasi mudah, sifat optoelektronik yang baik, mobilitas elektron tinggi, dan peningkatan efisiensi yang sangat signifikan dari 3.8 % pada tahun 2009 menjadi 25.5% pada tahun 2021. Namun, penggunaan logam Pb yang bersifat racun serta penggunaan material pengangkut hole (hole transport materials, HTM) yang mahal menjadi tantangan dalam pengembangan sel surya perovskite dalam skala besar. Penelitian ini bertujuan untuk mensimulasikan sifat-sifat fundamental pada sel surya perovskite tanpa Pb (lead-free) dengan CH3NH3SnI3 sebagai lapisan aktif dan graphene oxide (GO) sebagai HTM menggunakan Solar Cell Capacitance Simulator (SCAPS). Pada simulasi ini, analisis tentang pengaruh ketebalan perovskite dan interface defect perovskite/HTM terhadap karakteristik sel surya perovskite telah dilakukan. Hasil penelitian sel surya perovskite dengan konfigurasi FTO/TiO2/CH3NH3SnI3/GO/Au menunjukkan kinerja optimal dengan JSC = 31.64 mA/cm2, VOC = 0.813 V, FF = 74.76 % dan PCE = 19.25 %. Hasil penelitian ini dapat digunakan untuk memperkirakan parameter penting dalam optimasi sel surya perovskite tanpa Pb menggunakan GO sebagai HTM. Selanjutnya, studi pemodelan ini memberikan informasi penting dalam memilih parameter material untuk pengembangan sel surya perovskite yang efisien dan dengan biaya rendah.

Abstract: Carbon dots have gained much interest due to their outstanding optical and electrical properties, making them useful for a wide range of applications. Here Empty fruit bunch (EFB) biochar was used as a carbon source in a straightforward, environmentally friendly, and reproducible hydrothermal method for producing carbon quantum dots. In this study, the role of the hydrothermal process was seen and studied by comparing the shape and fluorescence. Exciting results from HRTEM show that the carbon quantum dots in the sample are 4 nm in size. The obtained CD emits bright blue luminescence, and the absorption peak of the carbon dots was observed in the UV region with maximum absorption at 205 nm and 322 nm. The light CD shows an intense sky blue color upon illumination by a UV-light source at 365 nm. The intensity of the photoluminescence (PL) spectra sharply increases with decreasing concentration of carbon dots. Meanwhile, the CD exhibited excitation-dependence, photo-stability, and well dispersibility. These results suggest that the present CD are potential applications in optoelectronics and imaging.Abstrak: Karbon dots telah menarik banyak perhatian karena sifat listrik dan optik yang luar biasa, sehingga dapat digunakan untuk berbagai aplikasi.

On August 20 of this year, the VMK-Optoelektronika company – a leading Russian developer and manufacturer of spectral analytical equipment – celebrated its 30th anniversary. The company was founded by the team of developers that initially worked in the Spektr temporary inter-institutional collaboration group created in 1988 by the Chairman of the Presidium of the Siberian Branch of the Academy of Sciences Academician V.A. Koptyug to develop multichannel analyzers of optical spectra based on domestic photodiode arrays and operate them at the academic institutes of the Siberian Branch. Over the past period, the company has developed and produced multichannel analyzers of emission spectra (MAES) based on photodetector array assemblies to equip existing spectral instruments in analytical laboratories and create new ones; a wide range of spectrum sources; high-resolution high-aperture spectral devices; atomic emission spectrometers for the analysis of powders, metals, and liquids. Currently, enterprises in Russia and the CIS countries operate: - more than 600 spectral systems for atomic emission analysis developed on the basis of existing spectral devices by replacing photographic plates and photomultipliers with MAES analyzers; many of these systems also include Sharovaya Molniya and Vezuvii electric-arc and spark-discharge generators, Globula and Kristall spectroanalytical instruments, Potok electric-arc facilities for atomic emission analysis of powder samples by the spill-injection method, and other devices; - about 100 atomic emission spectrometers entirely consisting of devices developed by the company. The company has a leading position in the development of scintillation atomic emission spectral analysis of geological powder samples and simultaneous multielement electrothermal atomic absorption analysis of liquids.

<p class="AbstractEnglish"><strong>Abstract:</strong>. Nonlinear material becomes the key material of modern information and communication technology. Developments of Optoelectronic device such as ultrafast switching, high-capacity information modulation, optical logic gates, and power divider waveguides are the direct application of nonlinear materials. In the practice of utilizing nonlinear materials, light sources have a vital role. This is due to the amplification of the intensity of the light source can cause the appearance of nonlinear effects. During this amplification of light intensity is done through doped fiber amplifier (DFA). The price of EDFA on the market is quite expensive and the design of EDFA optical reinforcement system also requires a very high cost, including the procurement of tools and optical instruments used. In this study designed a device capable of intensifying intensity with relatively economical cost, using laser diode and wave superposition principle. In testing through the optical power meter, we have obtained the intensity value derived from 6 Visual Visual Fault Locator laser that is coupled using 1x8 splitter. In the absence of phase control, the results obtained that the number of lasers that produce the greatest intensity is a combination of 3 lasers. Whereas, in the combination of 6 lasers, there is less power than 1 laser, this indicates that phase control becomes very important for constructive interference to occur.</p><p class="KeywordsEngish"> </p><p class="AbstrakIndonesia"><strong>Abstrak:</strong> Material nonlinear menjadi material kunci atas teknologi komunikasi dan informasi modern.

Tujuan penelitian ini adalah memfabrikasi pandu gelombang optik model Y-branch berbasis material Tin (IV) Oxide (SnO2). Pandu gelombang optik model Y-branch dibuat dengan menggunakan metode laser cutting, dimana substrat pandu gelombang optik adalah akrilik dengan film/core pandu gelombang adalah SnO2 dan PMMA sebagai cladding. Proses kerja laser cutting yaitu dengan memfokuskan sinar laser pada substrat akrilik yang ingin dipotong dengan ukuran 25x15 mm2. Setelah proses pemotongan akrilik kemudian material SnO2 berupa gel dimasukkan ke dalam pandu gelombang Y-branch. Pengukuran output pandu gelombang Y-branch dilakukan dengan mengambil gambar laser dari penampang melintang (cross section) pada pandu gelombang kemudian diolah menggunakan perangkat lunak Image-J. Grafik pada perangkat lunak Image-J dapat digunakan untuk menganalisis hasil penelitian. Laser He-Ne dengan panjang gelombang sebesar 632,8 nm sebagai sumber cahaya masukan pada pandu gelombang optik Y-branch. Hasil penelitian menunjukkan bahwa nilai intensitas output 1 dan output 2 yang optimum dari pandu gelombang optik model Y-branch terdapat pada sudut percabangan 50 yaitu sebesar 58,8% (kanal 1) dan 41,2% (kanal 2), hal ini menggambarkan bahwa pandu gelombang Y-branch dengan sudut 50 merupakan pandu gelombang optik yang memiliki nilai luaran yang optimum sebagai pembagi daya (power divider). Dengan demikian, pandu gelombang optik model Y-branch berbasis material Tin (IV) Oxide berpotensi untuk terus dikembangkan sebagai bahan utama pada divais optoelektronika. Kata Kunci: pandu gelombang, pembagi daya, SnO2, laser cutting Abstract Optical waveguides are one of the most important passive devices in photonic systems and optical communication networks. Devices in optical waveguides can transmit and modify optical signals from one point to another which can function as a power divider, directional coupler, optical combiner, and optical switch. The purpose of this research is to fabricate a Y-branch model optical waveguide based on Tin (IV) Oxide (SnO2) material. The Y-branch optical waveguide model is made using laser cutting method, where the optical waveguide substrate is acrylic with the film/core is SnO2 and PMMA as cladding. The work process of laser cutting is by focusing the laser beam on the acrylic substrate to cut with a size of 25x15 mm2. After the acrylic cutting process, the SnO2 material in the form of gel is injected into the Y-branch waveguide. Measurement of the Y-branch waveguide output is done by taking a laser image from the cross section of the waveguide and then processing it using Image-J software. Graphics in Image-J software can be used to analyze research results. He-Ne laser with a wavelength of 632.8 nm as an input light source on a Y-branch optical waveguide. The results showed that the optimum intensity value from the Y-branch optical waveguide model at a branching angle of 50 with 58.8% (channel 1) and 41.2% (channel 2), this illustrates that the Y-branch waveguide with an angle of 50° is an optical waveguide that has an optimum output value as a power divider. Thus, the Y-branch optical waveguide model based on Tin (IV) Oxide material has the potential to be developed as the main material in optoelectronic devices.

Abstract:

Multichannel analyzers of emission spectra (MAES) are operated as part of more than six hundred systems for atomic emission spectral analysis at enterprises in Russia, the CIS countries, and others. Until recently, MAES analyzers used only BLPP-369M1 photodetector arrays, whose performance is sufficient for integral atomic emission spectrometry applications using bright sources of spectral excitation based, for example, on an arc or spark electric discharge. To solve problems where high temporal spatial resolution and high sensitivity are required, high-speed MAES analyzers have been developed based on two new photodetector arrays—BLPP-2000 and BLPP-4000. A number of optical spectrometers based on these arrays have been developed and put into production by the VMK-Optoelektronika company: Atomic emission spectrometers: Grand Globula and Ekspress arc and spark spectrometers for the direct analysis of powders by evaporation from the channel of a graphite electrode and for the analysis of metals; Grand-Potok arc spectrometers for the rapid analysis of powders by the spill-injection method; Grand-Ekspert and Favorit argon-spark vacuum spectrometers for the rapid analysis of metals and alloys; Grand-SVCh microwave-induced nitrogen plasma spectrometers and Grand-ISP inductively-coupled argon plasma spectrometers for the analysis of liquids; Kolibri-SVCh microwave-induced air plasma spectrometers and Pavlin flame atomic emission spectrometers for the determination of alkaline and alkaline earth elements in solutions. Grand-AAS high-resolution continuous-source electrothermal atomic absorption spectrometers for the simultaneous determination of elements in liquids.

Abstract:

The creation and implementation of new sources of sample excitation and spectrometers based on them into the practice of analytical laboratories raises many questions for researchers about the obtained analytical characteristics of new equipment and analysis methods. The most important characteristics of any method include detection limits, accuracy and reproducibility of the results obtained. Matrix elements can have a significant effect on these parameters. The paper shows a comparison of the change in the intensities of analytical lines of elements in the presence of matrix elements with ionization potentials of 5.13 - 10.48 eV (Na, Cu, Pb, Cd, Zn, In, Ga, Bi) in the concentration range of 0 - 1 wt %. on commercially available atomic emission spectrometers with microwave plasma Grand-MP ("VMK-Optoelektronika") and Agilent MP-AES 4100 (Agilent Technologies). It is shown that the magnitude of the matrix effect in these excitation sources depends on the ionization potential of the matrix element and the total energy of the analyte line. A significant effect of matrix elements with a concentration of up to 1% wt. on the intensity of spectral lines of atoms and ions of the sample. Elements with medium and high ionization energies practically do not affect the intensity of atomic spectral lines of impurity elements and lead to a decrease in the intensity of ionic lines. The influence of easily ionized elements is more pronounced - both depressing and amplifying effects are observed, probably caused by both a change in the concentration of electrons in the plasma, leading to a linear change in the equilibrium between atoms and ions, and a decrease in the plasma temperature. An increase in the power supplied to the plasma on the Grand-MP spectrometer leads to a decrease in the effect of easily ionized elements on the intensity of the spectral lines of the elements. It is shown that the plasma in the Grand-MP spectrometer has better resistance to matrix influences as compared to the Agilent MP-AES 4100, which is associated with a large plasma volume and a higher input power.

Abstract:

Mikro ve nano yapılı optoelektronik malzeme endüstrisinin temelini oluşturan, teknolojik ve bilimsel araştırmalarda önemli bir yer tutan ince filmler, son zamanlarda en çok çalışılan güncel araştırma konulardan biridir. Yarıiletken özelliğe sahip metal oksitlerin üretiminde son yıllarda hızlı bir gelişim sergilenmesi rağmen günümüzde ince filmler büyük ölçekli üretim için pek de uygun olmayan döndürerek kaplama (spin-coater) tekniği ile hazırlanmaktadır. Bu çalışmada birçok optoelektronik aygıt teknolojisinin ihtiyaç duyduğu SnO2 metal oksit malzemesi ticari boyutlarda, uygun kalınlıkta ve iyi morfolojik/optik özelliklere sahip olarak slot-die kaplama tekniği ile üretilerek büyütme optimizasyonu gerçekleştirilmiştir. Mevcut slot-die sistemi üzerinde çözelti konsantrasyonu, başlık-alttaş mesafesi, çözelti beslem oranı, kaplama hızı, tabla sıcaklığı gibi çeşitli parametreler değiştirilerek ortam koşullarında en uygun kaplama koşulları belirlenmiştir. SnO2 ince filmler büyük alanlı (25 x 75 mm) alttaşlara başarılı bir şekilde hızlı ve ekonomik slot-die tekniği ile kaplanmış ve literatürde yaygın olarak kullanılan döndürerek kaplama tekniği ile üretilen filmler ile kıyaslanmıştır. Üretilen ince filmlerin optik karakterizasyonları UV-Vis ve fotolüminesans (PL) spektrofotometreleri kullanılarak yapılmıştır. Yüzey ve kesit alan morfolojisi alan emisyon taramalı elektron mikroskobu (FE-SEM) ile karakterize edilmiştir. Bu çalışma slot-die tekniğinin kullanıcılar tarafından daha iyi anlaşılabilmesi ve çeşitli optoelektronik uygulamalarda farklı malzemelerin de bu teknik ile büyük ölçekli olarak üretilmesi konusunda önemli bir yol haritası sunmaktadır.
