Molybdenum oxide films were fabricated successfully by spincoating from Li+-doped peroxo polymolybdate solution via sol-gel technique.Their electrochemical and electrochromic properties were investigated by cyclic voltammetry and in-situ 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 X-ray 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.
