Cs0.33WO3 for smart window glass is a dingal material that has been found to have excellent near-infrared absorption properties in recent years. Also, it is known as the most popular near-infrared shielding material that has the visible light transmittance of higher than 75%, and the near-infrared shielding rate higher than 85%. For obtaining a smart window glass with heat-shielding performance and UV shielding performance, Cs0.33WO3 nano powder is often prepared into heat insulation coating at first.

According to the experts, Cs0.33WO3 nano particles indeed possess excellent NIR absorption and photothermal conversion property. Furthermore, the significant temperature increase of up to 55°C is sufficient for the killing of cancer cells. Thus, in addition to NIR shielding, the other applications based on their excellent NIR photothermal conversion property (e.g., photothermal therapy) are expectable and worthy of further investigation. Also, the NIR absorption property of cesium tungsten bronze is worth investigating.
