Nano cesium tungsten bronze, or nano Cs0.33WO3, may be applied for preparing a new type of infrared ultraviolet shielding material such as thermal insulation films, which may be used in architectural glass. What you may not know is that skin is more sensitive to ultraviolet light in winter than in summer.

This is because both the winter and spring seasons are the seasons with the lowest global ozone content in a year. The lack of the "protective coat" of the ozone layer, more than 95% of the sun's UVA (ultraviolet long wave) will penetrate the clouds unscrupulously. If there is no a heat insulation film, the ordinary glass can't resist the harmful radiation from ultraviolet rays. In this regard, experts say that cesium tungsten bronze nano powder is a new type of heat insulation material with excellent UV and near-infrared rays shielding effects. Therefore, the cesium tungsten bronze nanoparticles can be used as a heat-insulating film or thermal insulation coating for the construction of office buildings to shield most of the ultraviolet and infrared radiation from the sun.
