Abstract
WO3 thin films were fabricated by an electrophoretic deposition (EPD) process. As-deposited WO3 thin films was annealed at 100 degrees C for 24 hrs to improve the electrochromic properties with better cyclability. While the surface roughness decreased as a result of the annealing process, the film thickness increased. The annealed WO3 thin film showed better performance than the as-deposited film with a coloration efficiency of 41.5 cm(2).C-1.
