Metal surface enhanced fluorescence is a kind of light-matter interaction importantly,i.e.,the interaction of surface plasmon resonance and light emitters like as fluorescence molecule,atoms,and quantum dots etc.This interaction with great progress being made recently is a fundamental problem for many potential application fields.The surface plasmon resonance can concentrate the light to strongly enhance the excitation process,furthermore,the emission process is also modulated by the plasmonic nanostructures presenting a modified quantum yield,fluorescence decay lifetime,and emission directivity.That is to say,the electromagnetic environment of the emitters can be engineered through designing specific metal nanostructures,and then the spontaneous emission process becomes to be controllable at the nanoscale.Nowadays,the state-of-the-art experimental method allows us to investigate the surface enhanced fluorescence at single nano-objects and single molecule level at which the theoretical method can meet with the experiments well.In this review,some representative advances related to localized surface plasmon resonance enhanced fluorescence would be presented,specifically,the properties about surface enhancement intensity,emission directivity,fluorescence spectral shape,fluorescence lifetime,and emission polarization etc in surface enhanced fluorescence would be discussed in detail.
