Abstract

A layer of TiO2 nanoparticles with size of 100 nm was deposited onto a fluorine-doped tin oxide (FTO) conducting electrode via dip-coating technique, followed by sintering treatment. Multi-state electrodeposition-based electrochromic device was subsequently fabricated by sandwiching gel electrolyte between a modified FTO electrode and a flat FTO electrode. When applied with a suitable voltage, the fabricated device changed its optical state from transparent to mirror or black depending on whether the silver nanoparticles were deposited on the unmodified or the modified FTO electrode. The silver was reversely dissolved into gel electrolyte once the applied voltage was removed. The fabricated device exhibited transmittance below 1% in the black state and reflectance over 70% in the mirror state. Moreover, the transmittance increased to 11% after 2000 cycles, indicative of good device stability.
