Nano cesium tungsten bronze has excellent near-infrared shielding properties so that it is the best dingal material for the preparation of bedroom heat insulating glass coating. The coating has the highest transmittance in the visible light region and the lowest transmittance at 1100 nm in the near infrared region. In other words, such smart coating shields heat without affecting indoor daylighting.

Nano particle size cesium tungsten bronze is a tungsten bronze type material. Tungsten bronze can be prepared by the mechanochemical method. What is mechanochemical method? Mechanochemical method is a new method for preparing inorganic materials. It refers to the method of preparing nanomaterials by physical changes and various chemical changes of the material under the external force. Generally, the equipment for mechanochemical methods is a high energy ball mill. This method of preparing tungsten bronze has the characteristics of no heating, no special atmosphere protection, and the like.
