WO3 Powder Applied for New Electrochromic Device

WO3 powder can be used to make WO3 film, and then be used to produce a new electrochromic device that has been popular in the past, that is, an smart window, which is also known as an energy-saving window. It is the smart device in the home that is becoming the norm. Wherein, tungsten trioxide can be made into two types of films including crystalline tungsten trioxide film and amorphous tungsten trioxide film. So, what is the difference between the two films?

Experts say that although both crystalline WO3 film and amorphous WO3 film have electrochromic effects, they differ in the way they regulate light. The crystalline c-WO3 film mainly absorbs a certain range of light waves to achieve color change and light transmittance, especially in the near-infrared region. The amorphous a-WO3 film mainly achieves the purpose of coloration and light adjustment by reflecting a certain light wave, especially in the infrared region.
