Tungsten oxide electrochromic film may be applied for preparing heat insulation glass. Wherein heat insulating glass is a heat-insulating glass that has various functions such as heat insulation, UV protection, safety and high transparency. And tungsten trioxide electrochromic thin film is a smart film that can turn common transparent glass into such a smart thermal insulating glass. In recent years, with the focus on energy conservation in China, tungsten trioxide electrochromic thin films have been gradually applied to buildings.

Electrochromism has long been known. And most experts are familiar with nano tungsten oxide film – an electrochromic thin film. According to experts, large-area electrochromic devices, such as glass curtain walls, can be obtained by spraying. Spraying, which is widely used with highly efficient production rate, can be used to produce large area electrochromic devices.

As an electrochromic film, tungsten oxide film can be used to assemble an electrochromic window to achieve the purpose of thermal insulation and energy conservation. However, for the time being, in order to successfully industrialize the tungsten oxide smart window, it is necessary to develop a low-cost, high-performance electrochromic material.

Electrochromic glass can be assembled using a tungsten trioxide film as an electrochromic layer because tungsten oxide has excellent electrochromic performance. According to experts, the transmittance of such a smart device can be changed, that is, the function of smart glass can be changed, including the performance of shielding ultraviolet rays, near infrared rays, and transmitting visible light. Also, it reduces glare. So, do you know how to measure the intensity of the color change of an electrochromic device?
