The effects of different Ag layer thicknesses on the optical properties of WO 3 -Ag-WO 3 composite films are studied by magnetron sputtering. The research of WO 3 -Ag-WO 3 composite films reveals that the introduction of Ag layer is not conducive to improving the transmittance ability of the film, and the transmittance modulation amplitude decreases with the increase of Ag layer thickness. However, with the increase of the Ag layer thickness, the response time and the cycle stability of the films have been significantly improved. However, electrochromic performances will decline when Ag was sputtered too long. Taken together, in this experiment, when the sputtering time of Ag layer is about 6min, the electrochromic device assembled by composite thin film can obtain the most excellent electrochromic performances.
