Cs0.33WO3, which is also known as cesium tungsten bronze, is mainly applied for preparing heat insulation window glass. And the prepared glasses are often applied to the architectural and automotive windows to obtain solar control windows for blocking most of ultraviolet light (more than 99%) and near-infrared light (more than 85%).

According to the experts, an incident light is either reflected at the surface of the glazing, absorbed through the window, or transmitted. The absorbed light increases the temperature of the glazing and emits heat radiation outside and inside the window. But, if these windows equipped with Cs0.33WO3 heat insulation window glass, the absorbed light including most of the near-infrared light and the ultraviolet light will be blocked, and most of the visible light will be passed through the glass. The experts also introduced that total solar energy transferred inside the window, called Tts, is the sum of the transmitted light and the radiation inside, and represents a reference index of the solar control property of a window. You should take it into account when you choose heat insulation glass.
