Cs doped tungsten oxide may be applied for producing near infrared shielding material. And the prepared material not only possesses photochromic property (photochromism), but also has electrochromic property (electrochromism). Then, what do photochromism and electrochromism mean? Photochromism refers to the tendency of the obtained cesium doped tungsten oxide heat-insulating material to exhibit good shielding performance to ultraviolet and near-infrared in the ultraviolet region and the short-wave near-infrared region. And the near-infrared shielding trend is deepened after ultraviolet irradiation. Moreover, after…
