摘要：

Films of tungsten oxide have been formed by electro-deposition from solutions containing other transition metals. The electrolysis solution was prepared using hydrogen peroxide to dissolve the metallic tungsten. One other metal salt was added to this solution using cobalt, chromium, iron, molybdenum, nickel, ruthenium or zinc. Such multiple metal oxide films differ from pure WO3 and exhibit different cyclic voltammograms, ac impedance behaviour and uv-visible spectra. The diffusion coefficients of intercalating ions do not vary greatly with film composition. The resistances to charge transfer, measured using complex ac impedance, are affected dramatically by film com position.
