Cs Doped Tungsten Oxide Nanopowder Applied for Near Infrared Shielding Material

Cs doped tungsten oxide nanopowder, or cesium tungsten bronze nanoparticles, may be applied for producing near infrared shielding material such as transparent heat insulating coating. Such coating can meet the lighting requirements of the building. More importantly, it can block the heat from the outside in real life.

Experts introduced that the raw material nano particles size cesium doped tungsten oxide, as a transparent conductive oxide, can selectively absorb solar electromagnetic waves. At the same time, it has high transmittance in the visible region. And it has a high reflectivity in near-infrared light zone and a certain absorption capacity for ultraviolet light. Therefore, the heat insulating products of nano cesium doped tungsten oxide and the resin can be uniformly mixed to form a transparent heat insulating coating. And the obtained coating can be coated onto a glass substrate by a suitable spraying process to obtain a transparent heat insulating film of cesium tungsten bronze of high value.
