Cs0.32WO3 for producing thermal insulation dispersion liquid is cesium-doped tungsten bronze nano powder with excellent near-infrared shielding performance, so it is often prepared into highly transparent heat insulation coating or heat insulation film for applying to glasses of buildings or automobiles. Well, what is the effect of Cs doping? According to the experts, with the increase of Cs doping amount, the free carrier content in the cesium tungsten bronze structure also gradually increased. The higher the crystallinity of the obtained Cs0.32WO3, the more complete the crystal structure.

The experts also introduced that the near-infrared absorption rate of Cs0.32WO3 is closely related to the plasmon resonance of free carriers. When the free carrier concentration is increased, the surface plasmon resonance effect is stronger, so the near-infrared shielding performance of Cs0.32WO3 is also stronger. In other words, the thermal insulation effect of the thermal insulation dispersion liquid of Cs0.32WO3 will also be stronger.
