Mo doped tungsten oxide can be used to prepare electrochromic nano films. Specifically, some experts prepared some nano films by using MoO3-doped tungsten oxide as a raw material, and studied their electrochromic properties. The results show that:
Compared with the pure tungsten oxide nano film, the Mo-doped tungsten oxide nano film has higher electrochromic response rate and coloring efficiency, and the position of the light absorption peak shifts toward the high energy direction.

Experts said that this is because tungsten oxide powder is a transition metal oxide that can be modified by doping different elements, changing the doping amount, optimizing doping and compounding processes to improve its properties. And they also mentioned that the preparation method of the dingal material by doping tungsten oxide is divided into a solid phase method, a liquid phase method and a gas phase method according to different reaction environments.
