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.

Tungsten oxide nanoparticles may be used for producing an energy efficient building glass – smart glass. And the raw material WO3 nanopowder is cathode electrochromic material that can be prepared by pulsed DC reactive magnetron sputtering method, wherein the metal W and tungsten-titanium alloy are used as targets. The so-called cathode electrochromic material means that the material is colorless in the high-valent oxidation state, and is colored in the low-cost reduced state. In addition to W, there are mainly Mo, Ti, and the like.

Tungsten trioxide nanoparticles may be applied for producing energy efficient building glass. The prepared building glass is a type of smart glass. The raw material WO3 nano powder is a transition metal oxide. Nano particle size WO3 is also a cathodic electrochromic material. So, what is the electrochemical reaction of the cathodic electrochromic material?

Tungsten oxide nano particles for new energy efficient building glass are a kind of cathode discoloration material, which has large discoloration amplitude and good cyclic discoloration reversibility. Also, the tungsten oxide nanoparticles can be prepared by a method suitable for large-area production - a reactive magnetron sputtering coating method. And WO3 is the core material of choice for the preparation of solid all-inorganic electrochromic devices. These electrochromic devices are often applied in building.
