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 ° 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.
