Thick molybdenum trioxide (MoO3) films (ca. 120 nm) were successfully deposited by an aqueous solution-processed method based on direct dissolution of the powder of ammonium molybdate ((NH4)6Mo7O24∙4H2O) precursors in deionized water. X-ray photoelectron spectroscopy (XPS) and ultraviolet photoelect...
