Cesium tungsten bronze nanopowder is an inorganic powder that can absorb the near-infrared light and have thus been applied to transparent thermal insulation film possibly by activating surface plasmon effect of free electrons.

In recent years, people pay more attention to the problems of environmental pollution and energy resources shortage. So, the energy-saving building materials of high heat insulation, high heat preservation, high transparency and high ultraviolet shielding performance will have a wide application. Among these energy-saving products, the transparent thermal insulation film of cesium tungsten bronze nanopowder is often used in both building heat insulation glass and automobile heat insulation glass as such a smart film has the characteristics of energy conservation, safety and environmental protection, and thereby it is gradually occupying the thermal insulation film market. According to experts, lanthanum hexaboride is also inorganic powder with high near-infrared absorption characteristics. While it has the problem of easily reacting with oxygen and water in the air. So, its application in the heat insulation field is declining year by year. This means that the market for cesium tungsten bronze is expected to expand.
