摘　　要：以普通钠钙硅玻璃为基板,以Ti[O(CH2)3CH3]4和CeCl3.7H2O作为前驱物,在合适的Ce/Ti摩尔比例下,采用溶胶-凝胶法和提拉工艺制备CeO2-TiO2复合薄膜。热处理后的镀膜玻璃呈金黄色,但各个试样的颜色随着热处理温度的改变而有所区别。通过测试镀膜玻璃的色品坐标、透过率等,以探讨不同的热处理温度对CeO2-TiO2薄膜性能的影响。The composite thin films of CeO2-TiO2 with an appropriate molar ratio of Ce/Ti were prepared on glass substrates by sol-gel processing and dip-coating technique.The precursor sol was prepared from the precursor of CeCl3·7H2O and Ti[O（CH2）3CH3]4.The colors of films after being treated were golden and changed with different heat-treated temperature.The effects of heat-treatment temperature on the properties of the films were studied by testing the chromaticity coordinates and transmission curve of the films.
