Electrochromic WO3 thin film was prepared by using tungsten metal solution in hydrogen peroxide as a starting solution and by sol-gel dip coating method. The chemical modification was analyzed by FT-IR spectroscopy and the thermal analysis was conducted by DTA/TG method. DTA/TG analysis and XRD pattern showed that tungsten oxide crystal phase formed at 400°C. SEM microstructure also showed that about 20 nm sized crystals appeared in amorphous matrix at 400°C. In the view of electrochemical property, WO3 thin film which was heat-treated at 300°C and was amorphous had better than that of the crystalline phase.
