　　The coupling between the localized surface plasmon (LSP) and the surface plasmon polariton(SPP) mode of the metallic nanostructures can lead to a strong enhancement of the electromagnetic field, which has an important application in enhancing the fluorescence of the nearby emitters.Herein, Ag nanocube and Ag film composite structures were prepared to enhance the fluorescence of CdSe quantum dots (QDs) on top of the surface.The enhancement was found to be relative to the SPR peak of Ag nanocube and the thickness of Ag film.
