Electrochromic switching of electrodeposited ZnO + Zn_5(OH)_8Cl_2 films

摘要

This study reports the effect of optical switching of electrodeposited ZnO + Zn_5(OH)_8Cl_2 films on a gold electrode in a bath of 0.05 M Zn(NO_3)_2 + 0.1 M KC1. The coating turns black when cathodic polarization is applied yet when the current is removed the electrode immediately returns to a white colour. This optical effect is reversible and can be switched through various cycles.
