Nano particle size cesium tungsten oxide is heat insulating nanoparticles that may be used to prepare near-infrared shielding material such as transparent heat-insulating coatings, and then be applied to architectural glass to achieve the purpose of saving energy and reducing room temperature.

In order to save energy, there are also all kinds of coated glass and reflective film on the market, but they have some problems that hinder application and promotion. For example, although metal coated glasses can reflect part of the energy in the sun with good thermal insulation effect, but their transmittance in the visible range is often low. If used in buildings, it will affect the indoor lighting, but increase the lighting burden indoors in the daytime. However, cesium tungsten bronze thermal insulation coatings do not have the above disadvantages. Experts say that this kind of new thermal insulation material can not only block most of the heat in sunlight, but also has high transparency. Therefore, its visible light transmittance is high. And it will not affect indoor lighting.
