摘要：
Titanium dioxide (TiO2) thin films were deposited on fluorine tin oxide/glass and indium tin oxide/glass substrates by thermionic vacuum arc in this work. The deposited films phases were identified as anatase and rutile from X-ray Diffractions. The bandgap of the samples has been found 3.0 eV. The electrochromic properties of TiO2 thin films were investigated using cyclic voltammograms, chronoamperometry and chronocoulometric studies. Electrochemical cation intercalation was promoted using 0.1 M LiClO4 in propylene carbonate. Inserted/extracted charge, diffusion coefficient, coloration efficiency, optical modulation, and reversibility was calculated. Best results were obtained for TiO2/FTO sample with 18.6 cm(2)/C coloration efficiency. Deposited TiO2 thin films optical and morphological studies also covered. (C) 2017 Elsevier B.V.
