Abstract
A new wet process was developed for preparing a V2O5 thin film for use in an electrochromic display device. V2O5 powder was dissolved into a mixed solution of benzyl alcohol and iso-butanol to obtain a vanadium solution, which was then spin-coated on an ITO glass followed by a heat treatment at temperatures above 300°C, preferably at 400°C. The resulting crystalline V2O5 thin film was excellent in reversibility of the electrochromism.Keywords
