摘要: Symmetric and asymmetric EC cells are here fabricated using amorphous W03-Mo03-V205 films vacuum-evaporated on substrates prepared in electrolyte of lithium perchlorate propylene carbonate. Dependences the reflection spectra symmetric transmission applied voltage was investigated. Almost black displays were obtained with W03-Mo03 to which negative voltages (the reduced state) contrast ratio improved compared pure W03 V205. Reddish films, V205-Mo03 gave yellow bluish displays. Addition Mo03 60% - 40% V205 composition has properties, giving colors between brown yellow-green. Possible represented CIE (x, y) chromaticity diagram.
