摘要
以Ti(OC_3H_7)_4为先驱体,SnO_2:F镀膜玻璃为基板,采用常压化学气相沉积法制备了TiO_2/SnO_2:F复合薄膜。用扫描电镜、X射线衍射、紫外-可见一近红外透射光谱等手段对样品的物相和性能进行了研究。结果表明:金红石相的SnO_2:F底膜促进了TiO_2金红石相的形成:当基板温度为480℃时。TiO_2/SnO_2:F复合薄膜出现针状结构。但随着基板温度继续升高,针状结构消失。样品的可见光透过率随基板温度而变化,其值为60%～90%,基本满足建筑物的采光要求。当基板温度为530℃时,TiO_2/SnO_2:F复合薄膜的光催化性能最好。
TiO2/SnO2：F composite films were deposited by atmospheric pressure chemical vapor deposition with Ti（OC3H7）4 as precursors and SnO2：F coated glass as substrates. According to the results of scanning electron microscopy, X-ray diffraction, and ultraviolet-visible-near infrared transmission spectroscopy, the formation of futile TiO2 can be promoted by the insertion of the futile SnO2：F under layer. When the substrate temperature is 480 ℃, a needle-like structure appears in TiO2/SnO2：F composite films, and then disappears as the temperature increases. The optical transmittance in the visible region varies from 60% to 90% with the change of substrate temperature, and is suitable for the daylight demands of buildings. TiO2/SnO2：F composite film prepared at the substrate temperature of 530 ℃ has the best photocatalytic properties.
