Thin films of 3 d transition metal oxides, namely, TiOx, MnOx, CrOx, CoOx and NiOx were prepared by electron-beam evaporation. All of them exhibited electrochromic behavior not only in the aqueous electrolyte but also in the non-aqueous electrolyte such as 1 M-LiClO4/γ-butylolactone. These films were characterized by electrochemical and spectrophotometric measurements. The electrochromic charge capacity was also determined. Among these 3 d oxides, NiOx films were found to provide excellent characteristics such as the highest coloration efficiency and the stability after 105 times color-bleach cycle.
