Nano tungsten trioxide, one of the transition metal oxides, is more and more widely applied for producing exhibition hall heat insulating glass coating. Such coating is transparent for coating on the glasses of the exhibition halls to form an electrochromic film. And then, these glasses will turn into smart glasses.

You know, since the discovery of the electrochromic (EC) effect in transition metal oxides in the mid-1960s, intense research and development work spanning four decades has led to many exciting developments in the science and technology of this class of materials. Tungsten trioxide, or WO3, has emerged as one of the key materials, not only for EC devices such as smart windows, but for many other related applications. After many years of technology development efforts, WO3-based smart windows have finally emerged as a viable commercial product. It is reported that the nano tungsten trioxide smart window can shield heat and UV rays without affecting the daylighting.
