Nanorods/Nanostructral Vanadium Oxide Prepared bySpray Pyrolysis

Nanorods/nanostructural vanadium oxide thin film was prepared on glass substrates by Spray Pyrolysis technique at a substrate temperature of 450 degrees C. The precursor solution was obtained by 0.1 M concentrations of VCl3 in de-ionize water. The structural, optical and morphological properties of this thin film was investigated by means of UV-vis spectrophotometer, X-ray diffraction (XRD), atomic-force microscopy (AFM) and scanning electron microscope (SEM). The optical result show that the optical gap is equal to 2.38 eV. The structural investigation conducted by X-ray diffraction showed that V5O9 thin film was polycrystalline with anorthic structure. SEM and AFM images revealed the formation of interconnected nanorods.
