According to the experts, tungsten oxide can also be compounded with nanocrystals to obtain composite films with excellent electrochromic properties. Nanocrystals have the characteristics of large non-stoichiometric specific surface area, and excellent electrochemical activity, so that it can form heterojunctions with amorphous tungsten oxide. The composite film of this structure exhibits excellent electrochromic spectral modulation performance and faster electrochromic response speed, thus it can be applied to smart dimming glass. And it is believed that such a smart glass has wide applications in energy saving buildings.
