| 摘 要： | 采用溶胶-凝胶工艺,用提拉法在普通玻璃上制备TiO2-SiO2/SiO2复合增透膜。用紫外-可见光谱(UV-Vis)测试膜层的透射率,计算复合膜层的光学常数、折射率和膜层的厚度;用扫描电镜(SEM)观察膜层的表面形貌;研究TiO2-SiO2的比例以及热处理工艺对复合膜光学常数的影响。结果表明:溶胶的稳定性是整个工艺的关键与基础,溶胶中乙醇含量、陈化时间以及热处理制度会对膜层的折射率和厚度造成影响,从而导致整个复合膜的透过率变化。通过优化工艺,制备出在可见光范围最大透过率>98%、平均透过率约为95%的高增透膜,并对得到的结果进行详细地讨论。

| Abstract: | A process for preparation of TiO2-SiO2/SiO2 composite films on glass substrate by dip coating of sol-gel was described. The transmission was detected by Uv-Vis and the optical constants were deduced from the fringe pattern of the transmission. The surface topography of the films was analyzed by SEM. The influence of the content of TiO2 and the process of annealing on the optical constants was studied. It has been shown that stability of sol is critical in production of the films. The content of ethanol in s... |
