Films consisting of vertically aligned VO2 nanorods were grown on silicon substrates by thermally oxidizing a sheet of pure vanadium in a rough vacuum. These VO2 nanorods, when heated in air at ≥400 °C, were oxidized further into V2O5 in which oxygen defects were introduced. The oxygen-deficient V2O5 films exhibited intense photoluminescence at room temperature in the visible light range and interestingly, are sensitive to oxygen and hydrogen in the environment, suggesting the possibility of applying oxygen-deficient materials in sensing oxygen. This study provides an alternative idea to synthesize oxygen sensing materials.
