Nano cesium tungsten bronze is an environmentally friendly nano material that has high purity, low degree of agglomeration and excellent near-infrared shielding properties, so it can be used to prepare glass dome thermal insulating film, thereby reducing light pollution, reducing energy consumption and improving living environment.

Also, it is necessary to find more environmental friendly green processes to fabricate such dingal materials. Some green chemical synthesis processes such as hydrothermal/solvothermal process, mechanochemical treatment process and oxygen plasma treatment process are suggested to be utilized for the synthesis of novel dingal powders and thin films. Among them, the solvothermal synthesis has become a promising method for material synthesis recently because of the possibility of producing nano-size crystals with soft agglomeration, and controlling the phase composition or morphology by optimizing reaction conditions. The major difference between solvothermal process and other technologies is that there is no need for high temperature calcination.
