Electrochromism in WO x and W x Si y O z Thin Films Prepared by Magnetron Sputtering at Glancing Angles
This work reports the electrochromic evaluation of W x Si y O z and WO x glad thin films deposited by reactive magnetron sputtering at glancing angle. Their electrochemical properties were assessed by the analysis of cyclic voltammetry and chronoamperometry measurements in 0.1 M HClO4, whereas their optical properties were determined by studying their transmission and absorption spectra under operation conditions. Both types of thin films presented outstanding electrochromic properties characterized by a fast response, a high coloration and a complete reversibility after more than one thousand cycles.
