Cs doped tungsten oxide may be applied for producing infrared thermal insulation nano material, and thus be used in architectural glass to achieve thermal insulation effect. It is well known that solar radiation provides energy for every life activity on Earth. The bands of solar radiation mainly include ultraviolet light, visible light and near infrared. And the visible light and near infrared are the bands where solar radiation energy is concentrated. The heat is basically entered into the doors and windows through far infrared radiation.

Therefore, two problems that need to be solved urgently for building energy-saving glass are:
First, meet the lighting requirements of high transparency. In other words, it has high transmittance in the visible light band;
Second, meet the requirement of reducing energy consumption. That is, it has high blocking rate in the near-infrared band to block the radiant energy of sunlight.
In this regard, experts in the study of Cs doped tungsten oxide nanopowder, found that such nanomaterials can solve the above two problems, and thus achieve energy-saving purposes. Therefore, experts are paying more attention to the in-depth research of Cs doped tungsten oxide nanoparticles for the application of heat insulation.
