Cs0.32WO3 is a nanotechnology based thermal insulation material for manufacturing energy-saving window. You know, nanotechnology based materials were formerly used by space research, pharmaceutics and electronics, but in the last decade several nanotechnology based thermal insulation materials appeared in building industry. The most critical material of them is nano ceramic coating of Cs0.32WO3 nanoparticles.

According to the experts, such an energy-saving window can be prepared by coating the mixed dispersed solution of Cs0.32WO3 with organic silicon resin on glass substrate. The results of thermal insulation characterized by UV-Vis-NIR spectra show that NIR transmittance of glass substrate is 82% and that of the as-prepared energy-saving glass of high NIR shielding performance is only around 12%, which is reduced dramatically. Besides, such a NIR shielding window has high transparency to transmit visible light. In a word, the rod-like Cs0.32WO3 nanoparticles with high NIR absorption have promising prospects in the fields of automotive and architectural glass.
