Synthesis of Vanadium Bronze Films by Electrodeposition from DMSO₂ Melts for Electrochromic Application

Abstract

The vanadium bronze films were synthesized onto the ITO electrode by electrolysis in molten dimethylsulphone (DMSO₂)-V₂O₅ and DMSO₂-V₂O₅-LiNO₃ systems at the temperature about 150 °C. The obtained film was analyzed by x-ray diffraction. Moreover, the electrochromic (EC) reactions of the vanadium bronze film in room temperature solution of propylene carbonate (PC) or high temperature solution of DMSO₂ were investigated. The lithium vanadium bronze film was discussed on the basis for high temperature electrochromic materials.
