Nickel oxide (NiO) thin films were deposited by e-beam evaporation on glass and ITO coated glass substrates initially held at room temperature without post-heat treatments. The structural and optical properties were investigated using glancing incident X-ray diffractometer (GIXRD) and spectrophotometer. The electrochromic (EC) behavior of NiO thin film was investigated using electrochemical technique viz. cyclic voltammetry, constant current measurement, and chronoamperometry in 1 M KOH electrolyte. The transmittance modulation and switching time with different operating voltage were also studied.
