Cesium tungsten bronze nanopowder has the best near-infrared absorption property, so it is often used to prepare dining room heat insulating glass coating --- a new type of heat insulation agent of high transparency, for glass windows, for glass doors, and for glass curtain walls. In general, the transparent heat-insulating coating can achieve an infrared shielding rate of more than 90% at 950 nm, and achieve a visible light transmittance of 70% or more. Also, it is anti-glare, waterproof, dust proof, fireproof and anti-explosion.

But, do you know how to characterize the near-infrared absorption properties of the cesium tungsten bronze nanopowder? Some experts used the Lambda35 UV-Vis spectrophotometer produced in the United States to characterize the UV-Vis-NIR absorption properties of cesium tungsten bronze powder in the range of 300-1100 nm. Specifically, in the background of BaCl2, the expert pressed the cesium tungsten bronze powder onto the BaCl2 sheet and tested its absorbance to characterize the near-infrared absorption properties.
