Photochromic Material: Cesium Tungsten Bronze

Cesium tungsten bronze is a photochromic material with good photochromic properties, so it can be used to prepare a variety of transparent heat insulation materials including thermal insulation coatings, thermal insulation films and heat insulating glasses. And these functional materials are widely used in the glass windows or glass doors of the buildings or cars to play the role of heat insulation and heat preservation, thereby reducing energy consumption and reducing cooling and heating costs. Cesium tungsten bronze is one type of photochromic materials, and cesium tungsten bronze is the most well-known one.

So, what is photochromic performance? Photochromic performance refers to the phenomenon that a material can produce a product with different structure and spectral properties through a specific chemical reaction when it is stimulated by a certain light source, and changes its own color. Generally, the color change reaction has good reversibility. Photochromism is usually explained by the Faughnan model.
