title: Enhanced visible photoluminescence of V(2)O(5) via coupling ZnO/V(2)O(5) composite nanostructures.
abstract: V(2)O(5) films capped by a thin ZnO layer had been prepared by sputtering method at room temperature. The initial smooth films transferred to porous composite nanocrystals and nanorods after annealed at 500 degrees C, and enhanced visible light emission was observed. This tremendous enhancement was attributed to the coupling between V(2)O(5) nanorods and ZnO nanoparticles as well as the improved V(2)O(5) crystallinity. Prominent vibrational fine structures of the photoluminescence spectra were also observed.
