F-doped cesium tungsten bronze may be applied for preparing smart glass as it has good visible light transmittance and near-infrared shielding properties. And it is reported that F doping cesium tungsten bronze has higher visible light transmittance and better near-infrared shielding performance than undoped cesium tungsten bronze. This is because the fluorine atom replaces the oxygen atom, increases the band gap and generates carriers.

F-doped cesium tungsten bronze may be used for preparing electrochromic smart window with excellent near-infrared shielding properties, and therefore such smart window may be applied in energy saving reconstruction of building. While do you know how to prepare F doping CsxWO3 with better near-infrared shielding performance? It requires a discussion of the effect of precursor mixing order on F-doping cesium tungsten bronze.

F-doped cesium tungsten bronze for manufacturing smart window can be prepared by low-temperature hydrothermal method. For example, some experts have prepared F-doping cesium tungsten bronze with good near-infrared shielding properties by hydrothermal synthesis method, using cesium carbonate (Cs2CO3), tungstic acid (mWO3•nH2O) as raw materials, sodium fluoride (NaF) or hydrofluoric acid (HF) as fluorine source, and citric acid as inducer.

F-doped cesium tungsten bronze may be applied for preparing window heat insulation film. According to experts, the key to improve the near-infrared shielding performance of F-doping cesium tungsten bronze is to select a suitable heat treatment time and temperature. But what effect does heat treatment have on F doped cesium tungsten bronze?
