The intensity of Cy3 was found to be increased relative to that of Cy5 . 5 in the vicinity of the plasmonic antennas where strongly enhanced electric field intensity and optical density of states selectively increase the excitation and emission rates of Cy3 due to spectral overlap with the plasmon .
