Cs doped tungsten oxide nanoparticles have optical properties so that they are often prepared into heat insulation coating for applying to building glass or automobile glass to obtain smart window. Wherein, Cs doped tungsten oxide nanoparticles can be Cs0.33WO3 nanoparticles. According to the experts, Cs0.33WO3 nanoparticles can be synthesized with different annealing temperature, various concentration and controlled atomic ratio by using the traditional solid state reaction method.

You know, the traditional methods for preparing the hexagonal tungsten bronze CsxWO3 usually require high temperature and harsh reaction conditions, such as heating mixtures of WO3 with Cs salts in reducing atmospheres at 1000 °C. Recently, morphology and phase control of particles by soft chemical synthesis methods have attracted wide interest in the synthesis of many oxides such as ZnO, WO3, etc. However, there is limited work reported on the synthesis and characterization of CsxWO3 with controlled morphology by solvothermal reaction. Furthermore, the effects of ammonia annealing on the heat shielding properties of CsxWO3 have not been reported.
