  An emitter in the vicinity of a metal nanostructure is quenched by its decay
through non-radiative channels, leading to the belief in a zone of inactivity
for emitters placed within $<$10nm of a plasmonic nanostructure. Here we
demonstrate that in tightly-coupled plasmonic resonators forming nanocavities
"quenching is quenched" due to plasmon mixing. Unlike isolated nanoparticles,
plasmonic nanocavities show mode hybridization which massively enhances emitter
excitation and decay via radiative channels. This creates ideal conditions for
realizing single-molecule strong-coupling with plasmons, evident in dynamic
Rabi-oscillations and experimentally confirmed by laterally dependent emitter
placement through DNA-origami.
