A high-performance electrochromic Mo-doped WO3 film towards smart window

Abstract Mo-doped WO3 (Mo@WO3) thin film electrode was prepared through the hydrothermal method with convenient and inexpensive steps. The microstructure and characterization of Mo@WO3 thin film were studied through SEM, XRD, and EDS. The Cyclic voltammetry, Chronocoulometry, Transmission spectrum, and Optical transmittance response were studied by electrochemical workstation and optical fiber spectrometer. The results show that compared with single WO3 film, Mo@WO3 thin film improves the electrochromic properties, which provides a novel idea for electrochromic smart windows.
