摘要：

The nickel oxide (NiO) films were prepared from nickel acetate precursor by sol-gel dip coating technique. The films were characterized for their structural, compositional, morphological, optical, electrochromical and colorimetric measurement using X-ray photoelectron spectroscopy, scanning electron microscopy, cyclic voltammetry, optical transmittance studies and CIE system of colorimetric analysis. XPS measurements revealed that the films exhibited presence of NiO phase. SEM images showed a smooth and porous nature of NiO thin film. The EC device made up of glass/ITO/NiO/KOH/ITO/glass showed optical modulation of 51% and relative luminance difference of 49.45%, respectively. In addition to the aforementioned parameters, the coloration efficiency was found to be 49 cm(2)/C at 550 nm. (c) 2012 Elsevier B.V. All rights reserved.
