Abstract:

Photoresponses for various porphyrin films prepared by the electrolytic micelle disruption (EMD) method have been investigated in the indium-tin oxide / porphyrin / I3, I / Pt cell. The EMD film of an n-type porphyrin, 5, 10, 15, 20-tetra(4-pyridyl)porphyrin (T(4-py)P), exhibited a clear optical filtering effect (OFE), while not for the EMD films of p-type porphyrins such as (5, 19, 15, 20-tetraphenylporphyrinato)zinc(II) (ZnTPP). For the EMD-ZnTPP film, the photocurrents at 500700 nm were remarkably enhanced by increasing the film thickness. These photoelectrochemical properties were expl

Abstract The nanostructured ZnO thin films were successfully synthesized by rapid thermal oxidation of metallic zinc films without catalysts or additives. On the surface of thin films the formation of ZnO nanowires was observed. In the work, the optical and electrical parameters and photoresponses of the obtained ZnO thin films were investigated. Nanostructured thin films of the type have a promising potential for the use in optoelectronics, sensor technique and biomedical sciences

Abstract:

Tetrasubstituted indium or gallium phthalocyanines and their dimers bridged with various ligands were dispersed in a polymer thin film, which was spin-coated on silver thin film vacuum-evaporated on a glass slide. All-optical reflectance control was achieved by complex refractive index changes upon photoexcitation of phthalocyanines by nanosecond laser in such a guided mode geometry. They gave rise in less than ns pulse width, and a few to a few tens of microseconds decay characteristic to the lifetime of the excited triplet state. Repeated and reversible reflectance changes were achieved. Axi

Abstract:

A fast photoresponse is observed in a current-biased epitaxial YBa2Cu3O7 thin-film bridge structure exposed to 100 ps laser pulses. A bolometric response, with a pulse width of the order of 10 ns, dominates at temperatures close to Tc and at high laser fluences. At lower temperatures and fluences, the observed transient response contains distinct fast and slow components. Preliminary results indicate a pulse width for the fast component less than 500 ps. Application of a small magnetic field perpendicular to the sample increases the amplitude of the slow component while leaving the fast compon

Abstract:

The photoresponse of ordinary and high-T c superconductors depends critically on the hierarchy of relaxation times, such as the electron–phonon and phonon–electron scattering times, the time of phonon escape from a superconducting film and also the phonon return time. For thin films of cuprates, close to the superconducting transition the following components of transient response are identified. The picosecond photoresponse is attributed to the dynamics of nonequilibrium quasiparticles and Cooper pairs. The nanosecond response is described by the thermal boundary resistance (the Kapitza resis

Reduced graphene oxide (rGO) has attracted interest in its potential application in large area photodetectors owing to its ease of manufacture and wideband optical absorbance. Here, we report that thin rGO films produced via vacuum filtration of GO followed by reduction by immersion in L-ascorbic acid are capable of sensing light through a bolometric mechanism. The photoresponse of these rGO thin films can be further enhanced by dropcasting graphene quantum dots (GQDs) on the rGO surface. These GQDs were observed to increase the opacity of the rGO film and hence its absorptivity of light, ther

Abstract:

Purpose This study aims to explore the applicability of the sol-gel-derived GaN thin films for UV photodetection. Design/methodology/approach GaN-based ultraviolet (UV) photodetector with Pt Schottky contacts was fabricated and its applicability was investigated. The current-voltage (I-V) characteristics of the GaN-based UV photodetector under the dark current and photocurrent were measured. Findings The ideality factors of GaN-based UV photodetector under dark current and photocurrent were 6.93 and 5.62, respectively. While the Schottky barrier heights (SBH) for GaN-based UV photodetector und

Abstract:

Pure and Aluminium-doped ZnO (Zn1-xAlxO) x = 0 to 5 wt% thin films were deposited onto glass substrate by sol-gel spin coating method. The influence of various aluminium concentration in ZnO thin films on the structural, surface, optical and photoconducting properties were investigated. The GIXRD studies confirmed the polycrystalline nature with wurtzite structure of pure and Al doped ZnO films. Films with 1.5 % concentration of aluminium showed maximum absorption and transmission in the UV and visible regions respectively. The FESEM images showed crack free films with increasing grain boundar
