Electrochromic material can be classified into inorganic electrochromic material and organic electrochromic material, wherein WO3 belongs to inorganic electrochromic materials - the most studied inorganic electrochromic material. Usually, it is WO3 thin film that used to produce electrochromic devices. So, what are the applications of tungsten oxide electrochromic devices?

Experts say that tungsten oxide electrochromic materials have very attractive and broad prospects for use, because the smart glass produced by these materials has transparency, and can be adjusted freely in a wide range. It can also continuously change between multi colors. Besides, it has the characteristics of memory ding, low color change voltage, simple power supply, power saving, and small environmental impact. Therefore, it can be used as a large-area digital, text and image display device. It can be used in vehicles, optoelectronic regulators such as cameras and lasers, building doors and windows, and radios. It can also be used for image recording, information processing, optical memory, optical switching, holography, decorative materials and complete protective materials. In recent years, a variety of electrochromic devices have been developed, mainly including information display devices, smart windows, glare-free mirrors, and electrochromic storage devices. In addition, it also includes high-tech products such as color-changing sunglasses, high-resolution optoelectronic camera equipment, photoelectrochemical energy conversion and storage, and electron beam metal plate printing technology. Therefore, the application prospect of tungsten oxide is also very attractive.
