Mo-doping Tungsten Oxide Electrochromic Film Applied for Smart Window

Mo-doping tungsten oxide electrochromic film for smart window has a higher light modulation range than the tungsten oxide electrochromic film. As you may know, tungsten oxide has an optical band gap of about 3 eV, so it is a wide band gap semiconductor. And it is easy to form a non-ideal ratio compound. But why is the Mo-doped tungsten oxide electrochromic thin film having a higher light modulation range than undoped tungsten oxide electrochromic thin film?

This is because tungsten ions have a grain size close to that of molybdenum ions. The electron transfer of tungsten ions and molybdenum ions in Mo-doped tungsten oxide electrochromic thin film causes higher energy absorption. Therefore, the absorption band of Mo-doped tungsten oxide film is wider than the absorption band of tungsten oxide electrochromic film. Therefore, the tungsten oxide - molybdenum oxide composite electrochromic film has a higher light modulation range.
