Molybdenum oxide (MoO3) thin films were prepared by pulsed-laser assisted deposition (PLD) over a wide range of growth temperature, 30-500 degrees C. The chemical composition, crystal structure, and electrochemical properties of PLD MoO3 thin films were investigated as a function of growth temperature. It was found that the growth temperature, and hence the thermochemical reaction during ablation, strongly influences the structural characteristics and properties of the resulting films. The compositional stability was well maintained up to a temperature on the order of 400 degrees C, after which point the formation of compositional defects introduces structural disorder and hence the reduced phases. Electrochemical performance evaluation indicated that the PLD MoO3 films grown at temperatures 300-400 degrees C display charge-discharge profiles comparable to that of crystalline MoO3.
