Nickel oxide films are classified as electrochromic materials for which the optical absorbance (A) change under insertion (by electrochemical methods) of small cations like H+ (protons) and Li+. The coloration efficiency (CE) is defined for electrochromic materials as the change in the optical absorbance per unit of inserted charge Q, i.e, CE=(A1-A2)/Q, where Q is the inserted charge that promoted the (A1-A2) change in the optical absorbance of the nickel oxide film.
