Tungsten trioxide for manufacturing dining room thermal insulating glass coating is a multidingal inorganic semiconductor and a metal oxide that can convert near to mid-IR light and is tuned by changing particle size and shape in addition to chemical doping. For example, changing the oxygen depletion in tungsten oxide nanocrystals alters the carrier density and thus the location of the resonance.

It means that the tungsten trioxide particles used are tungsten trioxide particles under 100nm in diameter. And these tungsten trioxide nano particles are often doped with alkali metals for excellent optical properties. For example, the CsxWO3 is the tungsten trioxide doped with Cs metal. And it is promising for applications to near-infrared shielding. You know, nowadays, there are a lot of glasses in the design of dining room. So, it can easily cause a large amount of radiant heat to enter the dining room through the glasses. In this regard, the experts suggest that it is a good choice to apply the dining room thermal insulating glass coating of tungsten trioxide to these glasses, to reduce the radiant heat penetrating into the glass, thereby saving energy. In a word, such a smart coating solves the problems of heat insulation, sun protection, UV resistance, heat preservation and light pollution.
