Nano cesium doped tungsten oxide may be applied in thermal insulating glass to play a role of high heat insulation. According to experts, in the preparation process of cesium doped tungsten oxide, the absorbance of Cs doped tungsten oxide in the visible region and the short-wave near-infrared region gradually increases with the extension of the reaction time. The lowest point of absorbance occurs at the wavelength of 450nm. In the ultraviolet region and the short-wave near-infrared region, Cs doped tungsten oxide has a high absorbance. In a word, cesium doped tungsten oxide nano particles exhibit good ultraviolet absorption properties and short-wave near-infrared absorption properties.

Nano cesium doped tungsten oxide may be applied for preparing heat insulation coating and be used on transparent heat-insulating coated glass. As you may have known, compared with other architectural glass energy-saving technologies, transparent heat-insulating coated glass has the advantages of simple production process, high visible light transmittance, and high near-infrared shielding coefficient, so that it is expected to become the main energy-saving technology for building glass in the future.

Nano cesium doped tungsten oxide may be applied for preparing thermal insulation coating. The obtained coating material is a new type of heat insulation coating, which is environmentally friendly with various advantages such as high efficiency, thin layer, beauty and anti corrosion. And it is waterproof and fireproof. Such coating can absorb near infrared light and shield UV light so that it is suitable for coating glass, ceramic tile, metal and cement.

Nano cesium doped tungsten oxide may be applied for preparing near-infrared shielding material such as thermal insulation dispersion, thermal insulation film, and thermal insulation coating. And these heat insulation materials can be applied in the heat insulation of large-area architectural glass, such as, sun room and glass curtain wall, etc. Therefore, it can be said that such a material that shields light, mainly shielding ultraviolet light and near-infrared light with little influence on the passage of visible light, is a heat insulating medium of window film.
