Nano grain size cesium tungsten oxide, or cesium tungsten bronze nanoparticles, may be used to prepare window heat insulation film, and thus be applied to architectural glass to obtain heat insulation architectural glass. We all know that it is necessary to air a quilt in the sun after a long time of use. In fact, it is the ultraviolet light in the sun that plays a role of bactericidal effect.

However, although ultraviolet light has a bactericidal effect, it can also cause harm to the human body if you are excessively exposed to the sun. Also, whether it is the cold winter or the hot summer, the ultraviolet rays in the sun are everywhere. Moreover, nowadays, the atmosphere is thinner, the ultraviolet rays are getting stronger and stronger, and it is necessary to prevent ultraviolet rays, especially for architectural glass. In this regard, the experts proposed a solution - to apply a layer of heat-insulating film of cesium tungsten bronze nano particles on the architectural glass. The thin film can almost block the ultraviolet radiation. And it also has excellent heat insulation property. In a word, it has the effect of shielding infrared radiation and does not affect the lighting. It kills two birds with one stone.
