在TS = 350 - 450 ℃的温度范围内，通过喷雾热解沉积在加热的玻璃上制备纳米晶二氧化钛（TiO 2）薄膜。薄膜的光学透射光谱分析表明，对于厚度为0.8 μ m ~ 1.6 μm的TiO 2薄膜，光学带隙约为3.2 ~ 3.4 eV，透射率大于80%。X射线衍射（XRD）分析表明，薄膜的晶体结构为立方相。AFM照片显示了组分的纳米尺寸。讨论了薄膜厚度和沉积温度对样品结晶尺寸和结晶度的影响。
Nanocrystalline titania (TiO2) thin films prepared by spray pyrolysis deposition on to the heated glass in a temperature range of TS = 350 ÷ 450oC. Analysis of optical transmission spectral of films reveals an optical band gap of about 3.2÷3.4 eV and the transmittance above 80% for TiO2 films with thickness of 0.8÷1.6 µm. X-ray diffraction (XRD) analysis demonstrates that the films are found of anatase phase in crystal structure. The AFM photographs show the nano-size of the constituents. The crystallize size and crystalline of the samples is discussed with respect to the film thickness and deposition temperature.
