F-doped cesium tungsten bronze has better near-infrared shielding properties than cesium tungsten bronze so that it may also be used to produce heat insulation coating, which may be applied to building or automotive glass to play the role of heat insulation and energy conservation. Wherein, experts said that the rod-shaped F-doped CsxWO3 has better near-infrared properties, and HF is likely to promote the formation of F doping cesium tungsten bronze nanorods.

F-doped cesium tungsten bronze has excellent near-infrared shielding properties so that it may be used to produce near-infrared shielding material such as thermal insulation film, thermal insulation dispersion and thermal insulation coating. In this regard, experts say that surface plasmon resonance is considered to be one of the sources of near-infrared shielding properties of cesium tungsten bronze.

F-doped cesium tungsten bronze may be applied for manufacturing a thermal insulation paper, that is, a transparent heat insulating film. But do you know what the change in morphology of F doping cesium tungsten bronze crystals with the increase of HF added is? We can analyze from the following figure - SEM images of F-doped cesium tungsten bronze with different HF addition amount. Wherein, (a), (b), (c), and (d) are undoped CsxWO3, CsxWO3 sample of F=0.11, CsxWO3 sample of F=0.45, and CsxWO3 sample of F=0.79, respectively.

F-doped cesium tungsten bronze may be used to prepare an environmentally-friendly transparent thermal insulation film, which is also a transparent conductive film. In this regard, experts say that the square resistance can not only indirectly characterize the thickness of the conductive film, but also characterize the permeability of the infrared spectrum. And it is generally considered that in a transparent conductive film, the lower the square resistance, the better the shielding property against infrared rays. Conversely, the higher the square resistance, the worse the shielding property to infrared light.
