A Study on Electrochemical and Optical Characteristics of } Electrochromic Thin Film Prepared by Different Constant Potentials and Deposition Time

In this study, the electrochromic thin film of tungsten oxide (WO 1-x ) was electrodeposited on indium tin oxide/glass (ITO/Glass) by potentiostatic method. The electrochemical characteristic and optical characteristic were analyzed by different deposition time, and the electrochromic behaviors of t...

Description
Summary:In this study, the electrochromic thin film of tungsten oxide (WO 1-x ) was electrodeposited on indium tin oxide/glass (ITO/Glass) by potentiostatic method. The electrochemical characteristic and optical characteristic were analyzed by different deposition time, and the electrochromic behaviors of the WO 1-x /ITO/Glass were performed in a 0.1 M lithium perchlorate/propylene carbonate (LiClO 4 /PC) electrolyte. The deposition time of WO 1-x thin film was set at 1200 seconds, which optimal transmittance variation (ΔT%), and coloration efficiency (η) were 73.2% and 53.4 cm 2 /C, respectively.
