Abstract

The electrochromic properties of $WO_{3}$/$MoO_{3}$ and $MoO_{3}$/$WO_{3}$ double-layers have been systemically studied. The double-layers were made by a e-beam evaporation method and investigated by studying optical modulation, transmittance, and cyclic voltammetry. The devices exhibit good optical properties with wavelength range of 400 to 1100 nm(visible and infrared) during coloration as a function of lithium ion charge injection. It has shown that the double-layer electrochromic thin films are improved the electrochromic properties, but the electrochemical properties are less stable.
