Abstract

This paper reports on fabrication of tungsten-oxide (WO3) electrode films on a transparent conducting coated glass substrate by cathodic arc plasma (CAP) technique. The influences of various oxygen deliveries on structural, optical and electrochemical properties of WO3 electrode films were investigated. X-Ray Diffraction (XRD) analysis indicated that the crystal structures of WO3 electrode film were amorphous which porous and columnar form exhibited high-rate ion injection/ extraction into/out of WO3 electrode films. We have demonstrated better Electrochromic Device (ECD) performance based on prepared WO3 electrode film with O2/Ar=5, that enhanced electrochromic properties in terms of shorter coloration/bleaching response times and better cycling durability. The impressive colored/bleached cycle, good ion diffusion coefficient (4.52��10-9 cm�²/s), high optical transmittance difference (~74%), high deposition rate (~15 nm/min) and fast coloration and bleaching times (7 s and 6 s) are suggesting that columnar arrays of WO3 electrode film deposited by the CAP technique is the promising smart window for potential electrochromic application.
