摘要

Photoluminescence of europium complex, Eu(III)DPA, where DPA is dipicolinic acid, in the presence of 5 nm-diameter Ag nanoparticles, was studied. Pronounced enhancement of Eu(III) luminescence was observed in the complex solution containing Ag nanoparticle with a concentration below 3.0 x 1013/ml. The dependencies of emission intensity of ~5D_0→~7F_2 and ~5D_0→ 7F_1 transition on the concentration of Ag nanoparticles are quite different, the enhancement of electric dipole transition is stronger than that of magnetic dipole transition. There is no significant change in fluorescence lifetime in enhanced luminescence. The enhancement was attributed to a strong coupling between the radiation transition and surface plasmon resonance.
