摘要
V 2 O 5 nanorods with remarkable visible light emission were synthesized by heating a V2O3 thin film in air at ∼530 °C due to the involvement of oxygen defects. The density of defects in the nanorods can be decreased by applying a magnetic field of 5 T during this transition, resulting in drastic decrease in the intensity of the photoluminescence of the V2O5 nanorods. The dependence of the defect removal on the magnetic field and the mechanism for this influence were also investigated.
