Nano grain size yellow tungsten oxide has photochromic property so that it may be used in heat insulating window glass to shield heat and beautify your car. Also, it is anti-explosion and anti-glare with long working life. Why it can shield heat? As the heat is mainly produced by near infrared rays and ultraviolet rays in sunlight, and yellow tungsten oxide block these rays. And why it can beautify your car? As the yellow tungsten oxide film shows up dark blue in color, which looks beautiful.
Yellow tungsten oxide is also a typical electrochromic material. Besides, yellow tungsten oxide is a common gas sensitive material, which is a semiconductor material developed in recent years with excellent gas sensitivity and gasochromic property. Compared with the electrochromic system, the gaschromic system has simple structure, few influencing factors, all solid materials, wide optical adjustment range, convenient large-area production, and no energy consumption for device operation, so it has more practical application prospects.
