摘　　要：随着国家节能减排力度的加大,国家建筑节能政策和设计标准均要求建筑业采用低辐射玻璃来实现门窗节能降耗。低辐射玻璃因其较低的红外线辐射率,使其具有优异的节能效果。Ag系低辐射玻璃中功能层Ag膜具有较低的电阻率和较高的红外线反射率,其沉积质量决定着低辐射薄膜的电学和光学性能,主导着低辐射玻璃的节能效率。文章分析了低辐射建筑节能玻璃应用的制约因素,阐述了低辐射玻璃的制备方法和节能原理,综述了改善功能层Ag膜沉积质量和提高薄膜低辐射性能的方法及途径,即适当调整工艺条件、合理选用介质层材料及进一步优化膜层结构等,展望了低辐射建筑节能玻璃的发展前景。As the nation is making greater efforts to save energy, low-emissivity （Low-E） glass is applied in windows and doors to save energy, which is required by the building energy policies and design standards. Low-E glass has excellent energy-saving effect due to its low infrared emissivity. The electrical and optical properties of Low-E films and the energy saving efficiency of Low-E glass are dominated by the deposition of Ag film due to its low resistance and high infrared reflectivity. This paper analyzes the limitations of applying Low-E building energy saving glass, reviews methods to improve the deposited quality of Ag film and enhance the low-emissivity performance of films after it describes the preparation and energy saving principle of Low-E glass, including appropriate adjusting of process conditions, rational using of material dielectric layers and further optimizing of the composite structure. At last, the development prospects of low-E building energy glass are pointed out.
