Cs0.33WO3 is a new type of near infrared shielding material. And it can also be said to be a new type of dingal material that can be made into a variety of near-infrared shielding materials such as thermal insulation film and heat insulation coating. According to the experts, heat-insulating film of Cs0.33WO3 can transmit most of visible light (wavelength 380 nm – 780 nm), cut off most of infrared light, and absorb most of light in the near-infrared band. That is to say, such a thin film can meet the requirements of light transmission and heat insulation.

Also, it is reported that the near-infrared shielding material made of Cs0.33WO3 nano particles meets environmental protection requirements. In theory, it can save households more than 30% of electricity consumption. It is expected to significantly improve the energy efficiency of household electricity consumption. Moreover, it will not pollute the environment and release harmful substances, such as formaldehyde.
