Nano tungsten oxide may be used in heat insulating window glass, which is mainly to shield the ultraviolet (UV) and infrared rays, thereby reducing the temperature inside the car and improving the comfort of human body. Tungsten oxide can also be used on electrochromic devices with excellent electrochromic properties. And therefore, such electrochromic devices will have shorter color change response time, i.e., higher color conversion rate. This requires that the entire color change reaction have higher reaction rate under the…
