Amorphous WO3 film has a good electrochromic effect, so it is a well-known and the most widely studied electrochromic material, more specifically, an inorganic electrochromic material. So, why does an amorphous tungsten trioxide film have a good electrochromic effect?

The reason why the amorphous tungsten trioxide film has a good electrochromic effect is that its crystal lattice is a three-dimensional disordered network structure. In addition to the formation of a quadrilateral channel, there are also triangle channel and pentagonal channel. This structure forms a polygonal channel that facilitates the rapid transmission of ions. For example, the electrochromic efficiency of the ester-doped film is high, indicating that there are many void channels inside the film suitable for ion transport, and the film is porous. As you may have known, the electrochromic property of WO3 film determines the dings of the prepared smart glass, so it is necessary to do a in-depth research on electrochromic performance of tungsten trioxide film.
