| Abstract: | Nb2 O5 polycrystalline nanofibers with different cyrstal structures were prepared by electrospinning method .The morphology and structure of the nanofibers were characterized by SEM , XRD techniques .The results suggested that the as-synthesized nanofibers exhibited high crystallinity , uniform size-distribution ,high aspect ratio and excellent continuities .T he diameter of the nanofibers could be controlled by modifying the electrospinning voltage . The hexagonal phase ,orthorhombic phase ,monoclinic phase and orthorhombic/monoclinic mixing-phase nanofibers could be obtained at different annealing temperature and atmospheres . |
