Abstract
In this work, we report the role of structure on electrochromic behavior of nickel oxide thin coatings deposited via chemical vapor deposition on ITO-coated glass in (EtCp)2Ni–O2–Ar and (EtCp)2Ni–O3–O2–Ar reaction systems. The structure and chemical composition were analyzed and then correlated with electrochemical response and transmittance modulation when immersed in 1 M KOH electrolyte. The NiO exhibits an anodic coloration, reaching an optical density modulation of 0.66 between colored and bleached state at 550 nm, with a color efficiency of 30.7 cm2C-1. Very fast switching between states was obtained, the coloration and bleaching time did not exceed 0.05 sec.
