Cesium tungstate for large area glass curtain wall is Cs0.33WO3 nanomaterial, which can be synthesized by a combination of the methods of co-precipitation and a nano grinding process. And the prepared nanoparticles can be characterized for its structural and optical properties using XRD, SEM, TEM and VIS-NIR absorption spectroscopy.

The results showed that Cs0.33WO3 nanopowder absorbs near-infrared, so that is can be used to prepare heat insulation coating for applying to large area glass curtain wall. In this research, the experts also evaluated the Cs0.33WO3 nano particles with its effect on the electrical output of a thermoelectric device when the hot side of the device is spun with thin film incorporated with Cs0.33WO3 nanomaterial. And they found that the Cs0.33WO3 nanoparticles absorbs the regime of near-infrared (NIR) wavelength spanning 900nm up to 2200nm, which is a main contributor of heat energy that may be utilized for electrical generation.
