Query: Spectral tunability of a plasmonic antenna with a dielectric nanocrystal   We show that the positioning of a nanometer length scale dielectric object,
such as a diamond nanocrystal, in the vicinity of a gold bowtie nanoantenna can
be used to tune the plasmonic mode spectrum on the order of a linewidth. We
further show that the intrinsic luminescence of gold enhanced in the presence
of nanometer-scale roughness couples efficiently to the plasmon mode and
carries the same polarization anisotropy. Our findings have direct implications
for cavity quantum electrodynamics related applications of hybrid
antenna-emitter complexes.
