Nano cesium tungsten bronze is the best dingal material for preparing heat insulation window glass. And the prepared smart glass can display excellent shielding properties under the spectrum of UV and NIR lights irradiation with high visible light (Vis) penetrating feature.

According to the experts, the coating can also display excellent VOCs (HCHO or/and toluene) decomposing properties under the full spectrum of UV, visible and NIR lights irradiation. In this case, the shielded NIR light by composites is further utilized instead of wasting as heat. In this process, the small polaron can jump from localized states to conduction band of CsxWO3 under irradiation of NIR (730?nm–1100?nm) and result in a NIR-catalytic reduction. It provides some indications into the fabrication of the energy-conservation and depollution catalysts as smart window coating with excellent optical characterization and photocatalysis performance. And it is believed that the heat insulation window glass of nano cesium tungsten bronze will have a wider application in the future.
