Cs0.32WO3 for preparing energy-efficient window is a nano dingal material with high visible light transmittance and high near-infrared shielding performance, which is of great significance in energy saving and environmental protection. You know, the automobiles are becoming more and more popular and the demand for cars is constantly increasing. It put forward higher demands on glasses of autos, which are the main channel for energy and light exchange between the interior and the outside of the car. It requires the glass must shield UV rays and infrared rays to achieve high thermal insulation, and ultimately reduce energy consumption of air conditioning.

Therefore, transparent heat-shielding coating with a high transmittance of visible light as well as with a high absorption of NIR light is of great significance for energy-saving and environmental protection, especially for applications of automotive windows. Cesium tungsten bronze (Cs0.32WO3) is a kind of non-stoichiometric semiconductor material with narrow band gap and exhibits high transparence of visible light and intense absorption for NIR light with wavelength longer than 1100 nm. It also has the advantages of low price and no toxic elements, so it’s expected to be applied as transparent insulation coating instead of ITO and ATO materials. It means that energy-efficient window of Cs0.32WO3 nanoparticles will be popular in the future.
