摘　　要：采用溶胶-凝胶法制备TiO2/SiO2复合薄膜,在TiO2/SiO2溶胶-凝胶体系中掺杂表面活性剂十六烷基三甲基溴化铵CTAB,通过简单提拉、迅速蒸发溶剂、后期热处理去除表面活性剂的方法制备出具有纳米结构的有机掺杂TiO2/SiO2复合光学薄膜.利用红外光谱(IR)研究掺杂薄膜表面的结构特征;利用紫外分光光度计UV-VIS-NIR研究不同实验条件下制备的复合薄膜吸收透过性的影响;结合椭偏仪和分光光度计等手段对实验结果进行测量,研究了在实验室条件下TiO2/SiO2复合薄膜的性能及制备方法,结果表明,实验条件对TiO2/SiO2复合薄膜的制备非常重要.TiO2/SiO2 composite films was prepared by sol- gel method. IR , UV- VIS- NIR spectropho- tometer and ELLIP are used to characterize the optical properties and surface microstructure of the film. and spectrophotometer method the experimental results were measured, studied under laboratory condition preparation of TiO2/SiO2 composite film. It has been prepared with variable refractive index of sol, the deposition of SiO2 thin films refractive index in 1.18 - 1.41 between adjustable, TiO2 film refractive index in 1.80-2.20 between adjustable. By ellipsometer, infrared speetrophotometer, UV- visible spectrophotometer, properties of the composite film were studied. The results show that experimental conditions about preparation of TiO2/SiO2 composite film are very important.
