Full textThe strong progress evidenced in photonic and optoelectronic areas, accompanied by an exponential development in the nanoscience and nanotechnology, gave rise to an increasing demand for efficient luminescent materials with more and more exigent characteristics. In this field, wide band gap hosts doped with lanthanide ions represent a class of luminescent materials with a strong technological importance. Within wide band gap material, zirconia owns a combination of physical and chemical properties that potentiate it as an excellent host for the aforementioned ions, envisaging its use in different areas, including in lighting and optical sensors applications, such as pressure sensors and biosensors. Following the demand for outstanding luminescent materials, there is also a request for fast, economic and an easy scale-up process for their production. Regarding these demands, laser floating zone, solution combustion synthesis and pulsed laser ablation in liquid techniques are explored in this thesis for the production of single crystals, nanopowders and nanoparticles of lanthanides doped zirconia based hosts. Simultaneously, a detailed study of the morphological, structural and optical properties of the produced materials is made. The luminescent characteristics of zirconia and yttria stabilized zirconia (YSZ) doped with different lanthanide ions (Ce3+ (4f1), Pr3+ (4f2), Sm3+ (4f5), Eu3+ (4f6), Tb3+ (4f8), Dy3+ (4f9), Er3+ (4f11), Tm3+ (4f12), Yb3+ (4f13)) and co-doped with Er3+,Yb3+ and Tm3+,Yb3+ are analysed. Besides the Stokes luminescence, the anti- Stokes emission upon infrared excitation (upconversion and black body radiation) is also analysed and discussed. The comparison of the luminescence characteristics in materials with different dimensions allowed to analyse the effect of size in the luminescent properties of the dopant lanthanide ions. The potentialities of application of the produced luminescent materials in solid state light, biosensors and pressure sensors are explored taking into account their studied characteristics.
O progresso observado nas últimas décadas na área da fotónica e optoelectrónica, acompanhado de um desenvolvimento exponencial nas áreas da nanociência e nanotecnologia, resulta numa constante procura por materiais luminescentes eficientes com características cada vez mais exigentes. Matrizes de largo hiato energético dopadas com iões lantanídeos assumem-se, atualmente, como uma classe de materiais luminescentes de elevada importância tecnológica. Dentro destas, a zircónia apresenta uma combinação de propriedades químicas e físicas que a potenciam como matriz para a incorporação dos iões mencionados, tendo em vista o seu uso em diversas áreas, destacando-se as aplicações em iluminação e sensores óticos, entre os quais sensores de pressão e biossensores. Associada à necessidade de materiais luminescentes com características superiores, encontra-se a necessidade de técnicas de produção rápidas, económicas e com potencial para produção em larga escala. Tendo em conta estas necessidades, técnicas como a fusão de zona com laser, combustão em solução e ablação laser em meio líquido são exploradas neste trabalho para a produção de monocristais, nanopós e nanopartículas de matrizes à base de zircónia intencionalmente dopadas com lantanídeos. Em simultâneo, é realizado um estudo detalhado das propriedades morfológicas, estruturais e óticas dos materiais produzidos. São estudadas as características luminescentes de matrizes de zircónia (ZrO2) e zircónia estabilizada com ítrio (YSZ) dopadas com vários iões lantanídeos (Ce3+ (4f1), Pr3+ (4f2), Sm3+ (4f5), Eu3+ (4f6), Tb3+ (4f8), Dy3+ (4f9), Er3+ (4f11), Tm3+ (4f12), Yb3+ (4f13)) e co-dopadas com Er3+,Yb3+ e Tm3+,Yb3+. Para além da luminescência de Stokes, foi avaliada e discutida a emissão anti-Stokes (upconversion e radiação de corpo negro) sob excitação no infravermelho. A comparação da luminescência em materiais com diferentes dimensões permitiu analisar o efeito do tamanho nas propriedades luminescentes dos iões dopantes. A discussão do trabalho é acompanhada por uma integração dos resultados visando as aplicações destes materiais luminescentes em emissores do estado sólido, biossensores e sensores de pressão.

The low energy, non-phototoxic, and deep tissue penetrative features of near infrared (NIR) light makes it a better biocompatible light source than direct UV irradiation for photolysis (bioeffectors photo-release) reactions when combined with upconversion nanoparticles (UCNPs). UCNPs can absorb NIR light and generate antiStoke-shifted (blue-shifted) emission including UV light. With NIR laser excitable and UV emissive properties of UCNP, it allows photolysis reaction (near the surface of UCNP) to be triggered upon NIR light irradiation. Using UCNP as a photo-release platform, the phototoxicity is lowered since excitation light source is replaced from UV to NIR. In this study, we screened several phospho-lipid formulations to surface-coating UCNP to study the colloidally stability and upconverting emission property in physiological solution. A photoresponsive peptide was tested for conjugation and photoactivation.

Light-cured (LC) composite resins are widely used in dental restorations, and are also applied as luting cements. Dental resin cements are polymerized by blue light irradiation, thus they are easily controlled, and fast cured in a short time. However, the polymerization of resin cements by blue light is hampered by the reduced transmission through the ceramics. Recently research reveals that Infrared (IR) light exhibits high transmission through dental ceramics. Our previous study also showed that the addition of upconversion phosphors (UPs) into LC composites could enhance the degrees of polymerization under NIR irradiation. The purpose of this study is to investigate if the addition of Ups into dental resin cements might enhance polymerization. The specific aims are to examine the thickness and type of dental ceramics, different combinations of blue light and IR, on the new polymerization pathway. The experimental material was Ups which absorbs NIR laser to emit blue light. First, the spectrum and irradiance of NIR laser and blue light emission were measured by a spectrometer. To examine the light transmission through ceramics, transmission of blue light and NIR through two ceramics (lithium disilicate ceramics and zirconia discs) of four thicknesses (0.3, 0.5, 0.8, 1.0, 1.5, and 2.0 mm) were measured by a powermeter. The experimental cement was prepared by adding 5% UPs into LC resin cement (VariolinkⅡA3 base). A multiphoton excitation microscopy was used to examine the excitation and emission lights of Ups and the particle distribution in resin cements. Subsequently, the blended cements were cured under two ceramics of different thickness with four blue light and adjunctive NIR combinations. The microhardness of cured cements was measured by a Knoop hardness test. The result shows that the NIR-UP conversion rate was 10.8%. NIR light exhibited about 1.8 time transmitted power of BL through both ceramics at 0.5 mm, and 1.7 time of BL power through 2 mm thick ceramics. The lithium disilicate ceramic allowed more light transmission than zirconia did. The UPs particle distributed homogeneously from top to bottom layers of the cement. From the microhardness test, NIR60 did not polymerize the cement to detectable hardness. Both BL40+NIR20 and BL20s+NIR40s showed higher hardness than BL60s did. The lithium disilicate ceramic groups exhibited higher surface hardness than zirconia. When increased NIR irradiation time from 20s to 40s and decreased BL from 40s to 20s, there were no significance difference in surface hardness. The application of this new materials and light curing technique on clinical ceramic cementation well improve the adhesion strength and quality significantly.

Up-conversion phosphor coated optical modulator in SOI wafer by utilizing the free carrier dispersion effect is fabricated. From the measured results, the longest emissive length pumped by 980 nm laser is about 4000 m, and the first device structure presents the modulation depth of 3.5% and the extinction ratio of -0.16 dB. Because the efficiency was too low, another way of preparing the phosphor film is thought out using the dip coating. The subsequent characterizations of these dip-coated films include the emissive spectrum and transmission / reflection / absorption measurements. A new device structure is also implemented. However, our second device so far has not demonstrated the modulation effect. The failure is possibly due to an ultralow emissive intensity of light being given off by phosphors, which is not strong enough to realize a noticeable SOI refractive index change.
