Mo Doped Tungsten Trioxide Nano Film

Mo doped tungsten trioxide nano film can be prepared by in-situ thermal oxidation spraying method. the doped tungsten oxide raw material can be prepared by a simple, green solution method. The obtained nanoparticles of a grain size of about 20nm, which can be uniformly dispersed in water to form a stable nano ink. So why to use an in-situ thermal oxidation spray technology to prepare a doped tungsten oxide electrochromic film?

This is because the doping process can introduce a large number of oxygen vacancy defects. If the in-situ thermal oxidation spraying method is used, the oxygen vacancy defects in the prepared nano particles can be eliminated while maintaining the structure of the thin film nanoparticles. And the light modulation range of the electrochromic film is improved. In addition, the film prepared by such spray method has good cycle stability, which is expected to replace the vacuum coating process with a very good application prospect in the field of electrochromism in the future.
