It has been reported that cesium tungsten oxide for producing heat insulation window glass has a superior performance over commercial ITO glass in both UV and short wavelength region of IR light. Wherein, cesium tungsten oxide can be Cs0.33WO3 nano particles.

Cesium tungsten oxide is often applied for manufacturing transparent heat-insulation film as it has excellent near-infrared (IR) shielding performance at the nanometer scale. And it is usually Cs0.33WO3 nanopowder. According to the experts, for bronze phase Cs0.33WO3, not only bandgap related UV light shielding, but also free electrons/mixed valence state related excellent IR shielding properties can be observed.

Cesium tungsten oxide is mainly applied for producing energy efficient glass window. And these windows are popular in modern buildings as they are “smart” to shield heat and pass through the visible light, thereby saving energy and ensuring daylighting.

Cesium tungsten oxide for preparing heat insulation window film is Cs0.32WO3 nano powder as it has excellent near-infrared region (NIR) absorbing ability. And these thin films are transparent for applying to buildings and autos. Well, Cs0.32WO3 nano particles can also be incorporated in the textiles to improve the heat utilization efficiency of solar energy.
