What Are Electrochromic Properties of Tungsten Oxide?

Tungsten oxide has electrochromic properties, which means that the color of tungsten oxide materials can change reversibly under the action of an external electric field. Typically, tungsten oxide is a colorless or pale yellow material. However, when an electric field is applied, tungsten oxide can undergo electrochromism, showing different colors, such as blue, green, purple, etc. This discoloration is due to the rearrangement of electrons in the crystal structure of tungsten oxide and the adjustment of the energy band structure caused by the applied electric field.

Specifically, when an external electric field is applied to the tungsten oxide material, the action of the electric field will cause the electrons in the material to move in the energy band. This electric field-induced electron movement leads to the adjustment of the energy band structure of tungsten oxide, thereby changing the absorption and reflection characteristics of the material for different wavelengths of light. Different energy band structure adjustments will lead to the appearance of different colors, thus presenting an electrochromic effect. The electrochromic properties of tungsten oxide make it useful in many applications such as smart windows, display technology, light regulation devices, etc. By adjusting the magnitude and direction of the applied electric field, the reversible change of the color of the tungsten oxide material can be realized, thereby realizing the regulation and control of light.
