用膜系设计软件设计了λ/4-λ/2的W型的双层减反射薄膜,优化了薄膜的光学常量,并使用溶胶-凝胶技术在玻璃基底上成功镀制了该双层折射率梯度的减反射薄膜.用椭圆偏振光谱仪、紫外-可见-近红外分光光度计、原子力显微镜等分析表征了薄膜的性能.结果表明,镀制了该双层薄膜的玻璃在400 nm～800 nm波段平均透过率增加了近6%,同时薄膜显示出了极佳的机械强度.

A type of two-layer SiO_2-TiO_2 antireflective (AR) coatings used in solar glass was introduced in this paper to improve the complicated two-step catalytic process and promote the mechanical strength of the coatings. Based on the coating design program, the reflectance of the two-layer (λ/4-λ/2 type) AR coatings and the optical parameters of the coating were designed and optimized. Meanwhile, the two-layer SiO_2-TiO_2 AR coatings was successfully coated on the glass substrate by sol-gel method. The performance of the coatings was analyzed with instruments such as Ellipsometer, UV-VIS-NIR Spectrophotometer, Atomic Force Microscopy. The results show that the average transmittance of glass coated in this way was increased by more than 6% at the wave band of 400 nm～800 nm. And the mechanical strength of the coatings is very well.
