Yellow tungsten oxide is more often called as tungsten trioxide (WO3). And discoloration property of yellow tungsten oxide refers to the excellent color-changing performance of tungsten trioxide such as electrochromic performance, photochromic performance, and gasochromic performance. These unique properties of WO3 make it have great application prospects in the fields of electrochromic devices such as smart windows, optical devices, and gas sensors.

So, do you know what is the discoloration property of a material? The discoloration performance of a material refers to the performance of a material under the influence of some external factors, such as changes in light, pressure, electric field, temperature, gas, solvent, etc., and the color change occurs. For example, tungsten trioxide changes its color and transparency under external electric field. Generally, this discoloration is reversible. And certain external conditions can be used to change and restore the color of the material.
