MoO3 thin films were successfully synthesized by a simple, inexpensive, and reproducible spray technique for gas sensing applications by using Ammonium molybdate tetrahydrat [(NH4)6Mo7O24.4H2O]10-2M aqueous solution. XRD shows that MoO3 prepared thin films crystallizes in an orthorhombic structure with space group Pnma (62) related to a-MoO3 phase. On the other hand, AFM observations show some fibers-shape parallel to the substrate. Finally, ethanol detection test shows good sensitivity with reproducible behavior
