Tungsten oxide used for producing nano transparent heat insulating glass coating is tungsten trioxide nanoparticles. The raw material WO3 nano powder is a nano material with good spectral selectivity, and thus the prepared coating is a spectrally selective coating. So what is a spectrally selective coating?

A spectrally selective coating is a type of dingal nano coating that selectively absorbs, transmits or reflects sunlight. Such coating can reflect part of the visible and infrared light in the sunlight, making the surface temperature of the architectural glass much lower than other coatings of the same transparency, to improve the working and living environment. Spectral selective coatings are used in a wide variety of applications. For example, the coating can be applied to the window glasses of a car to passively cool the car parked under the scorching sun. Certainly, such coating is more and more widely used in building glass for heat insulation and energy conservation.
