Cesium tungsten oxide, as a type of near-infrared shielding material, has high transmission of visible light. In other words, the dingal material of high heat insulation has high transmittance in the visible light band and high shielding performance in the near infrared band so that it can block the radiant energy of sunlight, thereby reducing the energy consumption in building and other aspects. Preparation of Transparent Heat Insulation Film of Cesium Tungsten Oxide Sodium tungstate and cesium sulfate were used…
