【 摘 要 】

Electrochromic (EC) properties of tungsten-molybdenum oxide (W1-yMoyO3) thin films were investigated. The films were deposited on indium tin oxide covered glass by reactive DC sputtering from tungsten and molybdenum targets. Elemental compositions of the W1-yMoyO3films were determined by Rutherford back scattering. Voltammetric cycling was performed in an electrolyte of 1 M LiClO4in propylene carbonate. An increase in molybdenum content in the EC films caused both a shift towards higher energies and a lowering of the maximum of the optical absorption band, as compared with WO3 EC films. Durability under electrochemical cycling was diminished for W1-yMoyO3EC films.
