Tungsten Trioxide Films

Tungsten trioxide film is a new type of functional material, which has a wide range of applications in smart windows, a large area flat-panel displays, gas sensor, and so on the field. But because WO3 Films still have some shortcomings, such as discoloration and sensitivity is not high, it will cause a lot of restrictions in the application. In order to improve its performance so that it can be widely used, the optimization can generally divided into three kinds: one is preparing a novel surface topography WO3 film.

The second is the preparation of nanometer WO3 composite film, third film doped WO3 modified. With further research to expand, need to find new chemicals, new fetters, explore preparation skills and preparation parameters appropriate to improve the surface appearance of the film become a hot topic. Currently, for performance optimization WO3 film discoloration research focused on electrochromic and temperament discoloration. And to improve its photochromic,less heat to research color and other properties. Future research in this area can be expanded.
