Cs doped tungsten oxide nanoparticles are often applied to produce transparent thermal insulation material such heat insulation film and heat insulation coating as the absorbance of such a dingal material is high in the near-infrared region, and the absorbance increases with the increase of the wavelength in the visible and near-infrared regions. But why does the absorbance of cesium tungsten bronze increase with the increase of wavelength in the visible and near infrared regions?
