F-doped cesium tungsten bronze for preparing energy-saving glass can be obtained by hydrothermal synthesis. Wherein, the raw materials are cesium carbonate and tungstic acid, the fluorine source is sodium fluoride or hydrofluoric acid, and the inducer is citric acid. And it was found that heat treatment at 500°C for 30min under N2 atmosphere is the best heat treatment process.

In addition, the expert prepared the F doped cesium tungsten bronze powder into thermal insulation coating and applied it to the glass by roll coating. They also studied the relationship between the preparation process and properties of F doping cesium tungsten bronze powder. Experts have found that the proper heat treatment temperature and time make the crystal structure of F doped cesium tungsten bronze crystal complete. And it also injects a stable F- into the cesium tungsten bronze lattice, thus further improving the near-infrared shielding properties of the fluorine-doped cesium tungsten bronze.
