The researches on the interactions between fluorophores and plasmonic structures have attracted many interests,which will not only be significant to understand the physical mechanisms of nano-optics,but also be helpful to develop novel plasmonic sensors1.In our previous works,we have demonstrated that the assembly of nanoparticle-film metallic junctions could efficiently turn on fluorophores attached on the metallic film from a quenching status to an intense directional radiation as surface plasmon coupled emission(SPCE)2,3.In this work,we will show that the SPCE properties are strongly dependent on the shapes of nanoparticles utilized for the plasmonic assembly.The silver nanoparticles of four different shapes(nanospheres,nanocubes,nanoplates,and nanostars)with similar dimensions have been fabricated for the study.The SPCE intensities increase in the order of nanoplates,nanocubes,nanospheres,and nanostars.The plasmonic assembly mediated SPCE displays unique responses to distance,varying with shapes of the assembled nanoparticles,which may benefit designs of interfacial sensors.This work would improve the detection capacity of SPCE,meanwhile facilitating the modulation of plasmonic fluorescence.
