Paper Abstract

Nickel-oxide films are prepared by rf sputtering, and their electrochromic properties are investigated. Sputtering atmosphere used is an Ar-02 mixture. The films obtained can be electrochemically colored and bleached reversibly in an 1-N NaOH solution, and are colored anodically. Colored film is dark brown, and bleached one is colorless and transparent. Maximum coloration efficiency obtained is 36 cm2/C at a wavelength of 640 nm. Coloration efficiency depends on total pressure of sputtering atmosphere, but is independent of oxygen content in the atmosphere.
