Tungsten bronze (CsxWO3) is a kind of non-stoichiometric functional compound with special structure of oxygen octahedron, which has low resistivity and low temperature superconductivity. In recent years, it has been found that CsxWO3 film has good near-infrared shielding performance, which is expected to replace the existing ITO conductive glass as a window material, and can be used as a good near-infrared heat insulation material, which has a very attractive application prospect in the fields of automobiles and architecture.
Nano Cesium Tungsten Bronze has the best near-infrared absorption characteristics. Usually, the transmittance at 950 -1400 can be less than 10% by adding about 2g per square meter of coating, and the transmittance at 550 nm can be more than 70%.

Applied range
1, the use in the film
Because of its unique molecular structure, Cs0.33WO3 particles have the characteristics of large specific surface area, good dispersibility, high strength and excellent optical properties, so they are very suitable for producing high-quality films. Compared with the ordinary film, the film containing Cs0.33WO3 material will have better insulation effect, flexibility and transparency.
2. Use in glass
Cs0.33WO3 nano-powder has good visible light transmittance and near-infrared light shielding performance, which can make the prepared glass products have better light transmittance and heat insulation effect, so it is suitable for building glass windows and car windows, which can effectively save the energy consumption of air conditioning and effectively prevent the aging of indoor items.
3, the use of textile fibers
Cs0.33WO3 has a strong absorption effect on near infrared rays (wavelength 800-1200nm) and is suitable for producing a new generation of textile fibers.
4. Other applications
Automobile film, PVB heat insulation laminated film, laser marking, laser welding, photothermal diagnosis and treatment, infrared filter, etc.
