Tungsten oxide powder may be applied for the preparation of nano-ceramic dispersion solution. Tungsten oxide also has electrochromic properties, in which the rate of discoloration of the material may be effectively increased by doping element. For doping element in tungsten oxide, most of the metallic elements that have lower electronegativity or weaker oxidizing ability than tungsten (W) are usually used, such as titanium (Ti), molybdenum (Mo), and vanadium (V), etc. The doping of these elements will change the crystallinity, grain…
