| 摘 要： | 探讨了在线温度和提拉速度对溶胶－凝胶法制备的ＳｉＯ２光学膜光学性质的影响，考察了热处理温度对ＳｉＯ２光学膜表面散射率的影响。结果表明：用溶胶－凝胶法制成的ＳｉＯ２光学膜随着在线温度的升高，膜的厚度呈线性减少，减少的速度为０．０９ｎｍ／℃；室温下ＳｉＯ２光学膜膜厚提拉速度呈指数增长，指数等于０．５４；ＳｉＯ２光学膜表面散射率随热处理温度的升高而增大，且在４００℃左右有一个增大的突变点。

| Abstract: | Si O2 thin films have been prepared on silicon substrates by sol- gel method in sols of dip- coating at room temperature. The thickness of thin films and optical properties are technologically dependent. The technology includes concentration of solution,raising speed,on line temperature and treated temperature.The influence of on line temperature and dip speed on opticalproperies of thin film isstudied.The refractive index of thin films increasing with on line temperature is resulted from the structural developing.The influence of treated temperature on the scattering index of film surface has also been investigated. |
