Figure 1

Schematic illustration of PL mediated by plasmonic and dielectric antennas: spontaneous emission (radiative channel, \({{\rm{\Gamma }}}_{R}\)) of a dye molecule attached to an Au nanoantenna (with the distance z to the Au surface) is suppressed by non-radiative losses (\({{\rm{\Gamma }}}_{NR}\)), while a Si particle enables radiative emission enhancement along with low non-radiative losses. A low-index (YVO4) particle has no near-field enhancement and negligible \({{\rm{\Gamma }}}_{NR}\).
