Structure, optical and electro-optical properties of polycrystalline WO3 and MoO3 thin films prepared by chemical vapour deposition

摘要: The structure and the optical properties of polycrystalline WO3 MoO 3 thin films prepared by chemical vapour deposition were determined. electrochromic characteristics these WO3-MoO mixed oxide investigated using protons as inserting ions. presence molybdenum in not only shifts maximum absorption peak towards higher energies but also improves performances films. transition metal oxides constitute a very interesting group materials because various that they exhibit ~. Recently, there has been great interest study effect shown films, generally disordered, materials. This phenomenon could be applied to large area display formation 2. Another possible application is regulation radiated energy through glasses, altering their transmission reflection ("smart windows") 3. Up now, existence this electro-optical demonstrated on many 4, its have found depend strongly method film preparation. Until we coatings (CVD) 5. structure, morphology, stoichiometry L6.
