Cs0.33WO3 for production of transparent thermal insulating film is also known as cesium tungsten bronze that exhibits the best near-infrared absorption due to its unique structure.

According to the experts, at a very little usage, cesium tungsten bronze produces a large near-infrared absorption with high visible light transparency. Such a strong absorption is derived from an extremely high molar absorption coefficient of cesium tungsten bronze. A weathering stability of cesium tungsten bronze against ultraviolet light and heat is high. And films of cesium tungsten bronze nano particles may show a color fade in high-humidity or hot water-immersed environments after being used a long time. A nanolayer surface coating of Cs0.33WO3 particles has been developed to improve stability against humidity significantly. As such a transparent thermal insulating film is more and more popular, the dingal material Cs0.33WO3 becomes publicly known in energy saving reconstruction of building.
