Applications of Yellow Tungsten Oxide

Due to its own unique characteristics, tungsten trioxide has huge application prospects in smart windows (i.e., electrochromic windows), large-area screens, anti-glare rearview mirrors, optical information storage, optical regulation, optical switches, optical device materials, optical information genetic materials, hydrogen sensors, NO2 sensors and other fields. So, WO3 powders of different particle size and WO3 films with different thickness have attracted much attention. For example, here has been significant advancement in WO3 smart window technologies in recent years due to their effectiveness in reducing energy consumption of indoor lighting and air-conditioning in buildings. Wherein, tungsten trioxide as the electrochromic material, in particular, has been widely studied as it provides a simple method for tuning or modulating visible light and infrared transmittance.
