| 摘 要： | 采用溶胶－凝胶法制备了纳米ＴｉＯ２薄膜，ＸＲＤ研究表明，纳米ＴｉＯ２薄膜随着热处理温度的升高，发生了从非晶状态向锐钛矿相的转变，最后转化为金红石相，ＵＶ－ＶＩＳ、俞 米ＴｉＯ２薄膜的致密度与成膜条件有关，Ｒａｍａｎ表明，随热处理温度的升高，纳米ＴｉＯ２薄膜的振动峰位发生移动，并且谱带明显宽化，表现出尺寸效应。

| Abstract: | Nanocrystalline TiO 2 thin films are prepared by the sol-gel process The structure of the thin films at different annealing temperatures are studied by XRD Using Raman and UV-VIS spectroscopy, the optical characteristics are studied, The results show that the Raman and UV-VIS absorption peaks of TiO 2 thin films shift to lower frequencey as the grain-size become small |
