Tungsten bronze is a selective light-transmitting material that can selectively transmit part of sunlight, such as visible light, so as to achieve the adjustment and utilization of solar energy, thereby helping to achieve green sustainable development.

Tungsten bronze, as a new type of transparent conductive material, has a suitable band gap (2.4 ~ 2.8eV) and a high concentration of free electrons. In addition, compared with traditional transparent conductive materials such as ATO, ITO, FTO, etc., tungsten bronze has many advantages such as low cost, non-toxicity, and strong light transmission ability, so it has become one of the current research hotspots. Wherein, cesium doped tungsten bronze with the formula of CsxWO3 is the tungsten bronze compound that has been studied more. CsxWO3 nano particles are often prepared into thermal insulation film or thermal insulation coating for applying to window glasses or glass curtain walls of buildings to reduce room temperature and save energy.
