Violet Tungsten Oxide Applied for Smart Window

Violet tungsten oxide for producing smart window is an electrochromic material. It is the violet tungsten oxide nano powder that makes common window become an advanced technology product to dynamically regulate the transmission of solar radiant energy.

For example, when it is hot, the windows are darkened, and the solar radiation energy in the room is reduced. In the cold weather, the windows become transparent, and the solar radiation energy reaching the room increases. Moreover, the color change process is done automatically. It means that the effects of heat insulation and heat preservation of such smart glass can be automatically adjusted.

Nowadays, electrochromic materials are outstanding in the field of heat insulation, especially tungsten oxides. So what is electrochromism? Electrochromism refers to the optical properties of a material that undergoes a stable, reversible color change under the action of an external electric field, and appears as a reversible change in color and transparency. The violet tungsten oxide nano particles can adjust the thermal insulation effect and the anti-ultraviolet effect of the smart glass during the discoloration process.
