Notes:
Electrochromic WO3 thin film was prepared by using tungsten metal solution in hydrogen peroxideas a starting solution and by a sol-gel dip coating method. The thermal analysis was conducted byDSC/TG method. A DSC/TG analysis and the XRD patterns showed that a tungsten oxide crystalphase was formed at 400oC. WO3 thin film when heat-treated at 300oC was amorphous and had abetter electrochemical property than that of the crystalline phase. Crystallization of tungsten oxidedecreased active sites of ion intercalation so that the current density decreased with heat-treatmenttemperature
