Cesium tungsten oxide powder is a new type of transparent near-infrared shielding material. And the obtained material is a transparent glass heat insulating material, which is widely used in construction and automobile glass. As you may know, transparent conductive films such as indium tin oxides (ITOs) and antimony tin oxides (ATOs) films have been used as transparent heat insulation materials. However, these materials can only isolate near-infrared light with a wavelength greater than 1500nm.
Cesium tungsten oxide (CsxWO3, 0<x<1) is a non-stoichiometric narrow bandgap semiconductor material with high visible light transmission and strong absorption of light with a wavelength greater than 1100nm. Compared with indium tin oxide and antimony tin oxide, cesium tungsten oxide has a blue shift in its near-infrared absorption peak, and therefore has received more and more attention. In a word, cesium tungsten oxide nanopowder is a very promising nano material in the fields of heat insulation.
