Cesium tungstate is mainly used to produce heat insulation film or thermal insulation coating for applying to green building glass curtain wall. Wherein, cesium tungstate has the formula of Cs0.33WO3 with nano particle size, and these glasses will become smart glasses with energy saving effect. As the problem of global warming, energy shortage and environment pollution became serious, people pay more attention to energy saving material. So, cesium tungstate, as an environmentally friendly material, is achieving great attention worldwide.

Well, it is reported that Cs0.33WO3 compound nanomaterial-incorporated thin film can enhance output of thermoelectric conversion in ambient temperature environment. And the material is synthesized through a combination of the processes of co-precipitation and wet nano grinding, and the characterization of its structural and optical properties was carried out using X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and visible-near-infrared absorption spectroscopy. According to the experts, this is because Cs0.33WO3 nanomaterial absorbs a range of near-infrared (NIR) wavelength spanning 900-2400 nm, of which the main contributor of heat energy may be utilized for electrical generation.
