Cesium-doped Tungsten Bronze Applied for Near Infrared Shielding Material

Cesium-doped tungsten bronze, or cesium tungsten bronze, is well-known as a near infrared shielding material, which can selectively absorb near-infrared light by localized surface plasmon resonance and polaron resonance. So, it is often used in the preparation of heat insulation coatings, heat insulation films and other heat insulation products. And therefore, it has broad application prospects in buildings and automobiles. Well, how to prepare cesium-doped tungsten bronze for near infrared shielding material?

According to the experts, they synthesized cesium-doped tungsten bronze nano particles by thermal plasma method. And they controlled the crystallite diameter in the range of 16 nm to 66 nm using the build-up method. In comparison with the breakdown method, the processing time of the wet pulverization process using the nano particles was reduced by about 80% at the maximum, and the suppression of light coloring was confirmed by the light resistance evaluation.
