摘要

In this study, we propose a straightforward method for x determination in sub-stoichiometric nickel oxide (Ni1-xO) films prepared by ultrasonic spray pyrolysis on fluor-tin oxide (FTO) substrates by varying the post-deposition thermal treatment. The Ni3+ concentration, the flat band potential (Phi(fb)) and the open circuit potential (V-oc) were determined by electrochemical impedance analysis in aqueous media and correlated to the transmission of Ni1-xO films. An x-ray photoelectron spectroscopy study was also performed to quantify the amount of Ni3+ in the films and compare it with the one determined by electrochemical analysis. The electrochromic behavior of the Ni1-xO films in non-aqueous electrolyte was investigated as well.
