本研究的目的是通过热处理尽可能地提高低发射率（low-e）玻璃的可见光透过率。这已经通过在具有热解低辐射氧化锡基涂层的商业玻璃的两侧上沉积二氧化硅（SiO2）的多孔薄膜来进行。选择SiO2是因为其折射率使其适合于未涂覆的玻璃侧和氧化锡涂层侧的抛光处理。减反射膜的沉积用浸涂方法进行，其中将基底浸入二氧化硅的溶胶-凝胶中。使用两种不同的二氧化硅溶胶-凝胶，一种是在实验室中制造的，另一种是具有较高孔隙率的商业溶液。对于用商业溶液生产的涂层，实现了积分可见光透射率（T-vis）增加9.8%点至0.915。还计算了窗口配置的U值、g值和T-vis。(C)2003 Elsevier B.

The objective of this study is to increase the visible transmittance of a low-emittance (low-e) glazing as much as possible by antireflection treatment. This has been carried out by depositing thin porous films of silicon dioxide, SiO2, on both sides of a commercial glazing with a pyrolytic low-e tin oxide-based coating. SiO2 was chosen because its refractive index makes it suitable for antireflection treatment of both the uncoated glass side and the side of the tin oxide coating. The deposition of the antireflective films was performed with a dip-coating method, where the substrate was dipped in a sol-gel of silica. Two different silica sol-gels were used, one was manufactured in the laboratory and the other one was a commercial solution with a higher porosity. An increase of the integrated visible transmittance (T-vis) by 9.8% points up to 0.915 was achieved for a coating produced with the commercial solution. Calculations of U value, g value and T-vis for window configurations were also performed. (C) 2003 Elsevier B.V. All rights reserved.
