CsxWO3, Cs-doped tungsten bronze, is a kind of transparent thermal insulation nanopowder. The Cs-doped tungsten bronze is usually a type of low resistivity material, in which there are generally a large number of free carriers, so that it has strong absorption on free carriers. And the absorption coefficient of free carrier (α) has a positive relationship with free carrier concentration and square of wavelength of absorbed light. Therefore, when the content of cerium (Cs) in Cs-doped tungsten bronze increases, the…
