Nano-structured molybdenum oxide thin films were deposited on glass substrates by spray paralysis methods with various rates of 1.5, 2.5 and 5 ml/min. Samples were characterized by FESEM images, XRD and UV-Vis spectra. The FESEM images indicated the formation of porous nano-rods covered with less than 50 nm fine grains sizes. Also we found the grown layers have an orthorhombic polycrystalline structure with characteristic orientations of (020), (040) and (060). XRD and also optical data analysis of the layers showed that with increasing the deposition rate, the crystallite sizes are increased and the band gaps of the samples are decreased. Among these samples, one which is deposited at 5 ml/min has the optimal structural conditions (the largest crystalline sizes and the lowest density of crystalline defects). It is found that the variations of the band gap in these samples are affected by the quantum confinement effect.
