【摘要】 在酸催化体系中以钛酸丁酯为前驱体制得TiO2溶胶,以正硅酸乙酯(TEOS)为前驱体制得SiO2溶胶,采用提拉法在普通载玻片上镀膜.辅助MASS膜系设计软件进行模拟计算,得到了透射比为99%的膜片.根据理论模拟结果,实验采用交叉镀膜,制备出了宽带增透TiO2-SiO2多层膜.用紫外-可见分光光度计测量了样品的透射光谱.实验发现,样品具有明显的宽带增透效果:在400~700nm波段,当光线垂直入射时,增透5.5%左右;45°角入射时,可增透10%.更多还原

【Abstract】 Titanic oxide sol and silicon dioxide sol are obtained by hydrolysis and co-condensation reactions occurred in acid-catalyzed system by carefully controlling the sol-gel process of tetrabutylorthotitanate and tetraethoxysilane（TEOS）.They are coated on glass slides by dipping method.In virtue of the thin film designing software MASS,broadband reflection reducing coating composed of TiO₂-SiO₂ multilayer films have been prepared.The transmission spectrum of the simulation is 99%.The transmission spectra of the samples are characterized by ultraviolet-visible spectrophotometer.For the case of vertical incidence,the average transmission of the slide sample increases 5.5% compared to the uncoated one in the spectra range from 400 nm to 700 nm,for 45°incidence the increase is 10%.更多还原
