AlN has weak piezoelectric property (piezoelectric coefficient d33=5.5pCN-1) and a high Curie temperature (>1150°C). By Sc-doping in AlN thin films, it is possible to synthesize ScxAl1-xN alloy with high piezoelectric coefficient and high temperature stability. In this study, c-axis oriented AlN thin films have been successfully grown on Si (100) substrates by DC magnetron reactive sputtering method. First-principles calculations are also performed to investigate the structure of ScxAl1-xN.

Pyroelectric lead lanthanum zirconnate titanate (PbLa8Zr65Ti35) thin films were prepared by a metal-organic decomposition (MOD) method on Pt(111)/Ti/SiO2/Si(100) substrate. After annealing at different temperatures with the same annealing time, the amorphous films were transformed into polycrystalline PLZT films. The phase formation and surface microstructure were investigated by X-ray diffraction (XRD) and atom force microscopy (AFM). The XRD data showed the formation of pervoskite phase at 650°C and indicated suppression of pyrochlore phase as temperature increasing. The PLZT pyroelectric sensor was fabricated based on sensitive barrier layer instead of the other type barrier layer. Finally, dielectric and pyroelectric coefficients was also measured.

We study the introduction of Zr as a third material within a nanometric periodic Mg/Co structure designed to work as optical component in the EUV range. Mg/Co, Mg/Zr/Co, Mg/Co/Zr and Mg/Zr/Co/Zr multilayers are designed, then characterized in terms of structural quality and optical performances through X-ray and EUV reflectometry measurements respectively. For the Mg/Co/Zr structure, the reflectance value is reported to be 50% at 25.1 nm and 45° of grazing incidence. Nuclear Magnetic Resonance (NMR) measurements are performed to study the nearest neighbour local environment around the Co atoms.

Thin films of V2O5, especially vanadium oxide films with nano- and micro-structures, perform well as cathode material for Li ion batteries and charge storage devices. Thin films of V2O5 with different porosity were obtained by dip-coating sol-gel technique. V2O5 sols were prepared by dissolution of V2O5 powder in benzyl alcohol and isopropyl alcohol in proper proportion. Optical property and porosity of films were characterized by FTIR and ellipsometer. Electrochemical characterization was recorded by chronopotentiometry(CP) and cyclic voltammetry(CV). Furthermore, the study shows that the porous structures of V2O5 films had an effect on the stability and reversibility of the films.

Magneto-optic properties of magnetic materials have much influence on the performance of these current sensors. For practical using, it is generally demanded that the sensing materials had the good magneto-optic properties of large Faraday rotation. Among the most attractive properties of the transparent materials containing Fe2O3 are those related to the magneto-optical effects. The Sol-gel processes are extensively used for the preparation of optical or magneto-optical nano-composite materials though the incorporation of metal ions in the silica matrix. In this study, the Nd2O3 doped Fe2O3-SiO2 nano-composite films with different concentrations of Nd2O3, heated temperature and the number of layers were prepared by sol-gel method. The dependence of Faraday rotation angle of films is studied at room temperature. We find that appropriate concentrations of Nd2O3 (Nd/Si=0.011) doped has improved magneto-optic properties of higher Faraday rotation angle, the θF value increases with the decrease of the temperature below 500°C, the absolute value of Faraday rotation angle increases as the number of layers increases.

Pure tungsten oxide thin films apparently show gasochromic performance, based on PdCl2 catalyst. In this paper, adulteration of MoO3 into WO3 sol has been achieved via sol-gel method. FT-IR, Differential Scanning Calorimeter (DSC-TG) and Uv-visible Spectroscopy have been used to analysis the compound sols, films and optical properties for the use of this material as smart windows. FT-IR shows that for the compound, new characteristic absorption bands arise, which is different from pure WO3 or MoO3. DSC-TG shows the phase change during the temperature ascending from 50 to 800°C. The compound thin films performs relatively well in coloring response time, colored extent, coloring-bleaching recycling and gasochromic effect with non-unicity color.

Anatase Ti1-xFexO2 (x=0, 1%, 2%) nanocrystalline films were prepared on quartz substrates by a facile nonhydrolytic sol-gel route. The structure and optical properties have been studied by X-ray diffraction (XRD), Raman scattering, transmittance spectra and temperature dependent photoluminescence (PL). The B1g, Eg and (A1g+B1g) modes of anatase phase TiO2 can be observed in Raman spectra. Dielectric functions have been extracted by fitting the transmittance spectra in the photon energy range of 0.5-6.5 eV with Adachi's model. The pure TiO2 film displays a strong broadening visible luminescence band; however, Fe-doped samples exhibit a very weak luminescence due to the increase of oxygen vacancy concentration in TiO2. With the temperature increases, the PL intensity decreases monotonously and there are five emission peaks for the pure sample in low temperatures, which could be attributed to oxygen vacancies, surface states and F+ center.

Tungsten oxide thin films were prepared by depositing WO3 onto glass substrates coated with ITO using reactive evaporation process at ambient temperature and 200°C respectively. The thin films were grown at different deposition rate. Chronoamperometry was carried out and spectral measurements were performed in situ. Results showed that the thin films prepared at low deposition rates possess higher coloration efficiency (CE), and the thin films grown at ambient temperature have high CE than those grown at 200°C. The origin of the differences in coloration efficiency of the thin films were analyzed and discussed based on the electrochromic mechanism of amorphous tungsten oxide films. The samples morphology was characterized by atom force microscopy (AFM).

Near-infrared-ultraviolet optical properties of Sn0.925Mn0.075O2 (SMO) film grown on c-plane sapphire substrate have been investigated by the transmittance spectra in the photon energy of 0.45-6.5 eV (190-2650 nm) from 5.3-300 K. The optical constants have been extracted by fitting the experimental data with the Adachi's model. The optical band gap of the film can be estimated from the relation (αE)2proportional to(hυ-Eg). It is found that the absorption edge shifts to a lower energy side with increasing the temperature and the band gap Eg decreases from 3.80 to 3.72 eV. The parameters αB and θB of the Bose-Einstein model are 45.4 meV and 221.8 K, respectively, which could be ascribed to the thermal expansion of crystal lattice and the carrier-phonon interaction. The band narrowing coefficient dEg/dT of the SMO film is estimated to be -3.92x10-4 eV/K at room temperature.

We are developing a hard X-ray telescope utilizing multilayer supermirrors. This telescope is conical approximation of the Wolter-I configuration with tightly nested shells. Because of the fact that different nested shell corresponds to different grazing incident angle, so the optimum multilayer design depends on the grazing angle, and one would therefore, ideally design a different coating for each of the nested mirror shells. However, as a matter of practicality, we have to reduce the number of different designs for a reasonable compromise between the complexity of the calculation and optimal performance. In this paper, we investigate the effect of different angular classification on the effective area of the hard X-ray telescope. Many groups of hard X-ray supermirrors are optimized with different grazing incident angles using a numerical and analysis method. These supermirrors are divided into different number of groups, e.g. two, four, six, eight, ten, twelve, fourteen, and sixteen, respectively, and the corresponding effective areas are calculated. Results show that six groups of X-ray supermirrors are suitable for a reasonable compromise between optimal performance and the complexity of the calculation and fabrication.
