Cesium tungsten bronze with the formula of CsxWO3 is well-known as a near-infrared shielding material. You know, there are many near-infrared shielding materials, but it is generally believed that cesium tungsten bronze is the most popular dingal nanomaterials for preparing building energy-saving materials such as thermal insulation coatings. According to the experts, the solar radiation energy reaching the earth's surface is mainly composed of ultraviolet light (<400nm), visible light (400nm-780nm), and infrared light (> 780nm). Among them, infrared light is an important part of sunlight and a major source of thermal energy.

In summer, infrared light passes through the glass to increase the indoor temperature and consume a lot of energy. In winter, indoor heat is easily lost through the glass. Therefore, in order to reduce infrared light entering the room through glass in summer and store this part of energy in winter to reduce indoor heat loss, a near-infrared shielding material - cesium tungsten bronze is often used to prepare heat insulation coatings and many other energy-saving products. In a word, CsxWO3 is helpful to solve the energy crisis and environmental pollution.
