Abstract

Abstract: Vanadium oxide thin films were deposited on stainless steel substrates at different temperatures using the Pulsed laser deposition technique. Post annealing effect on the better crystalline V2 O5 film was studied and found that the annealing had a positive impact on the crystallization. The structural and morphological properties were investigated by XRD, Raman, and SEM analysis. The presented work opens up the changes that occur in phase orientations and the tunable morphological growth in the Vanadium oxide thin films. The prepared thin films have potential applications in energy storage devices. Highlights: Crystalline V2 O5 and V6 O13 films were grown on SS substrates using a single target. Temperature induced morphology change from grains to nanorods in V2 O5 thin films. V6 O13 thin film with a slate like morphology is achieved.
