Abstract

Pure and Copper doped nickel oxide film was deposited on ITO-coated glass substrate by simple nebulizer technique at the substrate temperature of 350 oC. The effect of Cu content on NiO film’s optical and electrochromic properties was characterized by UV-Vis-NIR spectrometer and cyclic voltammetry respectively. As the Cu content increases the transmittance decreases, consequently the band-gap energy wanes from 3.32 eV to 2.78 eV. The transmittance of both bleached state and colored state were significantly lowered for 0%, 5%, and 10% copper doped samples.
