Yellow Tungsten Oxide Nano Powder Applied for Smart Window

Yellow tungsten oxide nano powder, or nano particle size tungsten trioxide, may be used to prepare a smart window, which is also known as an energy-saving window familiar to the public. Such window has excellent optical adjustment performance, which can achieve the effects of thermal insulation and environmental protection. Also, the smart glass is highly transparent so that it is more and more widely used in glass curtain walls, sunrooms and greenhouses. At the same time, tungsten trioxide is coming to the most people’s sight.

For the smart window, some experts use Prussian blue as the counter electrode to form the all-solid smart window of the tungsten trioxide electrochromic compensation structure, which is found to be a very useful research direction. This structure has a certain optical adjustment performance. However, this smart window has a problem of low transmittance (<50%) or high coloration state (>20%), which needs further study.
