Mo doped tungsten trioxide nanoparticles film is a new type of electrochromic film, which can be prepared by a spray coating method. Some experts used spray coating technology to prepare 10×10cm2 molybdenum doped tungsten trioxide electrochromic devices under laboratory conditions, and evaluated their electrochromic properties. They found that Mo doping has an effect on the response speed, cycle stability and other performance of the tungsten trioxide electrochromic film.

Experts say that by doping, not only can the electron conduction rate of the material itself be increased, but also the particle size of the tungsten trioxide can be significantly reduced, so that it can be uniformly dispersed in the aqueous solution. In addition, the experts also studied the effects of the drop coating method and the spray method on the electrochromic properties of tungsten trioxide. That is to say, these prepared electrochromic film are applied to obtain the smart glass.
