NOVEL WET PROCESS FOR PREPARATION OF VANADIUM-OXIDE THIN-FILM

Vanadium oxide thin film has been prepared from an aqueous solution sy stem of (V2O5-HF) with addition of aluminum metal by a novel wet prepa ration method called Liquid Phase Deposition (LPD). The as-deposited f ilm was amorphous and consisted of reduced-state vanadium ion. By heat treatment under air flow, the film was crystallized and oxidized to V 2O5. Electrochemical properties of the deposited films were observed. Crystallized film showed reversible color change when lithium was elec trochemically intercalated and deintercalated.
