Preparationandelectrochromicpropertiesof MoO3/WO3compositefilm

MoO/WO, composite films with different MoO, deposition cycles were prepared to use conductive glass as the substrate by combining hydrothermal method and electrochemical deposition method. Electrochromic reversibility, optical density (AOD), coloration efficiency, stability and responding time of MoO/WO: composite film were obtained by electrochomical measurement technologies and spectral tests. The results show that the MoO/WO, composite film with 8 MoO, electrodeposited cycles has the best electrochromic performance compared with single WO, nanorod film or MoO, film, and the electrochromic reversibility is 62. 19%, the optical density is 0.61, the coloration efficiency is 153. 16 cm(3)/C, the coloring and bleaching responding time is 8.37 3 and 4. 77 s. respectively. It the meanwhile, it has a narrower band gap and higher cyclic stability
