Plasma Assisted Facile Synthesis of Vanadium Oxide (V3O7) Nanostructured Thin Films

摘要

Vanadium oxides nanostructured thin films are synthesized using plasma assisted sublimation process. The effect of temperatures on growth of V2O_5 and V_3O_7 thin films is studied. Scanning electron micrographs shows different morphologies are obtained at different temperatures i.e. at 450 °C nano cubes-like structures are obtained, whereas at 550 °C and 650 °C nanorods are obtained. Sample deposited at 450 °C is entirely composed of V2O_5 and sample at higher temperatures are composed of mixed phase of vanadium oxides i.e. V_2O_5 and V_3O_7. As temperature increased, so the content of V_3O_7 in the sample is increased as confirmed by XRD and Raman analyses.
