Cesium tungsten bronze nanopowder is a new type of environmentally friendly dingal material. It is relatively inexpensive. It contains no toxic elements. And it does not pollute the environment. What is more important, cesium tungsten bronze has high visible light transmittance with strong absorption at wavelengths of greater than 1100 nm. Therefore, nano particle size cesium tungsten bronze is considered to be a smart material that is expected to replace ITO and ATO for the preparation of bedroom thermal insulating…
