Rare-earth(RE)ions have been widely applied to luminescent materials because of their unique luminescent properties that originated from 4F electron configuration,which include sharp luminescence band,long excited state life time,abundant emission bands,low luminescence backgrounds,etc.However,the low quantum efficiency of Ln3+ions has limited their applications,and efforts on the exploration on the efficiency improvement have never been stopped.Except for the traditional strategies,achievement in the field of plasmonics offers us an alternative way to enhance the luminescence emission of Ln3+doped luminescent materials.In current talk,we will report our recent investigation on the fluorescence enhancement with metallic nanoparticles for Ln3+doped luminescent hybrid nanosystem,.
