Abstract
Vanadium oxide thin films were prepared by spray pyrolysis using solutions of vanadium chloride (VCl3) with different concentrations on glass substrates heated at 200 and 250 °C. The influence of substrate temperature (Ts) and solution concentration (molarity) on structural and vibrational properties is discussed by using X-ray diffraction and Raman spectroscopy. The results revealed that at 0.05 M and Ts = 200 °C, V4O9 thin films are obtained. At 250 °C, V2O5 phases with preferential orientation are observed and the films become polycrystalline when the molarity increases.
