WO3 nanocrystalline can be used as an electrochromic layer to assemble a flexible electrochromic device, which has very high light transmission and very fast bleaching speed. For example, some experts have assembled liquid electrolyte flexible electrochromic devices with high optical transition rates based on WO3 nanocrystals and ZnO nanorod array electrodes.
