Abstract

Tungsten trioxide (WO₃) thin films have been prepared on the flexible indium tin oxide (ITO) substrates by pulsed laser deposition (PLD) using WO₃ targets in oxygen gas. Color of the WO₃ film on the flexible ITO substrates depends on the oxygen gas mixture. The plasma plume produced by PLD using a Nd:YAG laser and WO₃ target is investigated by temporal and spatial-resolved optical emission spectroscopy. WO₃ films prepared on the flexible ITO substrates show electrochromic properties, even when the substrates are bent. The film color changes from blue to transparent within 10-20 s after the applied DC voltage is turned off.
