Yellow Tungsten Oxide Nanoparticles Applied for Energy Efficient Building Glass

Yellow tungsten oxide nanoparticles may be applied for the preparation of energy efficient building glass, which is a new type of smart glass with high heat insulation performance and heat preservation performance. According to experts, that is because the raw material WO3 nanoparticles have excellent electrochromic properties. Certainly, experts introduced that other than WO3 nano powder, doped tungsten trioxide nano particles also have good electrochromic properties. Some experts have studied the effect of doping different concentrations of Ti on the electrochromic properties of nano particle size tungsten oxide.

Experts have found that as the Ti concentration increases, between 2% and 6%, the crystal structure of tungsten oxide changes from monoclinic to amorphous. When the Ti concentration was further increased to 10%, the XRD results showed a mixture of the monoclinic WO3 phase and the rutile TiO2 phase, and the fiber network structure was transformed into a granular shape at this time. In short, the cyclic stability of the film can be improved after Ti doping.
