Cs doped tungsten oxide nanoparticles, or cesium tungsten bronze (CsxWO3) nanoparticles, are dark blue powders. But, CsxWO3 nanopowder is sometimes called as transparent thermal insulation nanopowder as the heat-shielding products such as heat insulation films made of such a dingal material are highly transparent with excellent near-infrared shielding performance. Well, do you know how to measure the near-infrared shielding performance of Cs doped tungsten oxide nanoparticles?

According to the experts, the near-infrared shielding performance of cesium-doped tungsten oxide nanoparticles before and after ultraviolet irradiation can be studied by disposing the cesium tungsten bronze powder into a certain concentration of latex, coating it on a glass slide, and then analyzing the transmission spectrum of the coated glass. The results show that the near-infrared shielding performance of the CsxWO3 film after ultraviolet irradiation has been further improved. The experts also introduced that heat insulation films of CsxWO3 nano particles are welcomed for shielding heat of buildings and autos.
