Abstract: Molybdenum oxide films were fabricated successfully by spin coating from Li+doped peroxopolymolybdate solution via solgel technique.Their electrochemical and electrochromic properties were investigated by cyclic voltammetry and insitu UV transmittance measurements.The results showed that the films possessed excellent electrochemical stability and reversibility.The electrochromic mechanism of the MoO3 was discussed by using results obtained from Xray photoelectron spectroscopy (XPS).The results showed that the most part of the Mo6+ in MoO3 film was reduced to Mo5+ and Mo4+ ions during the Li+ intercalation process,Mo4+ was oxidized to Mo5+ and part of Mo5+ was oxidized to Mo6+ again during the Li+ deintercalation process.So it was considered that Mo4+ ions existed in the colored MoO3 films.
Key words: MoO3 films, Electrochromic, X-ray photoelectron spectroscopy (XPS)
