In this study, tungsten trioxide (WO3) thin films were electrodeposited on indium tin oxide (ITO) glass to form WO3-coated glass. The electrodeposition (ED) time (tED) and ED current (IED) were varied to control the film thickness and morphology. Furthermore, the crystallization of the thin films was controlled by annealing them at 250°C, 500°C, and 700°C. The results showed that the thickness of the WO3thin films increased withtEDandIED. The as-deposited thin films and those annealed at 250°C were amorphous, whereas the WO3thin films annealed at 500 and 700°C were in the anorthic phase. Moreover, the amorphous WO3-coated glass exhibited high transmittance in visible light and low transmittance in near-infrared light, whereas the anorthic WO3-coated glass had high transmittance in near-infrared light. An empirical formula for determining the thickness of WO3thin films was derived through multiple regressions of the ED process parameters.

The tungsten oxide (WO3) thin films on the indium tin oxide (ITO) glass in this study were produced by applying the electrodeposition method (ED). This method involves adjusting ED time to control the structure, film thickness, and morphology of WO3thin films. Furthermore, the crystallization of the WO3thin films was controlled by annealing them at 200 °C and 500 °C. The results show that the WO3coated glass with non-annealed and annealed at 200 °C has a high transmittance of visible light and anti-infrared characteristics. However, the WO3coated glass annealed at 500 °C has high infrared transmittance, with the highest infrared transmittance reaching 85% at the 1000 nm wavelength. To improve the heat collecting efficiency of solar water heaters, the high infrared WO3coated glass can be applied to the surface of the heat collecting component.

We have obtained Er-doped ZnO thin film in a micropattern of reverse trapezoids processed on Si substrate by sputtering and ultrafine polishing techniques. Near-infrared light emission was detected successfully from the thin film filling a single micropit with 10 μm square. Transmission electron microscopy (TEM) observation showed epitaxial growth of ZnO crystals along the curvature of the micropit.

This study describe the effect of temperature on the opticalproperties of nickel(ii) phthalocyanine tetrasulfonic acid tetrasodiumsalt (NiPcTs) organic thin films which are prepared by spin coatingon indium tin oxide (ITO-glass). The optical absorption spectra ofthese thin films are measured. Present studies reveal that the opticalband gap energies of NiPcTs thin films are dependent on theannealing temperatures. The optical band gap decreases with increasein annealing temperature, then increased when the temperature risingto 473K. To enhance the results of Uv-Vis measurements and getmore accurate values of optical energy gaps; the Photoluminescencespectra of as-deposited and annealed NiPcTs thin films was studied.FTIR measurements for NiPcTs thin films also carried out in thiswork and gave good information about the NiPcTs bonds and itslocations as a compared with H2Pc as a reference.
