α-V2O5 nanorods were grown by means of electron beam irradiation and thermal oxidation
methods and the visible emission properties of the nanorods grown by both methods were
investigated. The growth and crystallinity of the nanorods were greatly enhanced by the
insertion of a buffer layer. The emission spectra of the nanorods grown by thermal oxidation
and electron beam irradiation showed a peak centered at 710∼720 nm, which is believed
to be due to oxygen vacancies introduced during the growth process. Also, the emission
peak centered at 530 nm observed in the V2O5 nanorods grown by electron beam irradiation
was considered to be due to the band edge transition as a result of the enhanced crystallinity.
