Yellow Tungsten Oxide Applied for Large Area Electrochromic Glass

Yellow tungsten oxide can be prepared into a tungsten oxide film and then be used as an electrochromic layer material for assembling a large area electrochromic glass – a smart window for green building. Also, tungsten trioxide electrochromic film can be applied to produce display device and thermal control device. Increasing commercial applications make tungsten trioxide receive extensive research and more attention.

However, there is a long way to go for small area ​​electrochromic glass in the laboratory to be enlarged into large-area electrochromic glass that can be used in real life as many technical and technological problems are urgently needed to be solved. In addition, the cycle life and stability of electrochromic glass are also in urgent need of improvement. Furthermore, to industrialize large-area electrochromic glass, we must find a simple and inexpensive method for preparing large-area electrochromic thin films. As you may have known, common methods for preparing electrochromic thin films include magnetron sputtering, spray pyrolysis, screen printing and spray coating. In order to prepare large-area electrochromic glass, these methods need to be further studied to meet the requirements of industrialization.
