Facile Solution Synthesis of Tungsten Trioxide Doped with Nanocrystalline Molybdenum Trioxide for Electrochromic Devices.

ABSTRACT: A facile, highly efficient approach to obtain molybdenum trioxide (MoO₃)-doped tungsten trioxide (WO₃) is reported. An annealing process was used to transform ammonium tetrathiotungstate [(NH₄)₂WS₄] to WO₃ in the presence of oxygen. Ammonium tetrathiomolybdate [(NH₄)₂MoS₄] was used as a dopant to improve the film for use in an electrochromic (EC) cell. (NH₄)₂MoS₄ at different concentrations (10, 20, 30, and 40 mM) was added to the (NH₄)₂WS₄ precursor by sonication and the samples were annealed at 500 °C in air. Raman, X-ray diffraction, and X-ray photoelectron spectroscopy measurements confirmed that the (NH₄)_2<
