Abstract
Described embodiments include a plasmonic apparatus and method. The plasmonic apparatus includes a substrate having a first negative-permittivity layer comprising a first plasmonic surface. The plasmonic apparatus includes a plasmonic nanoparticle having a base with a second negative-permittivity layer comprising a second plasmonic surface. The plasmonic apparatus includes a dielectric-filled gap between the first plasmonic surface and the second plasmonic surface. The plasmonic apparatus includes a plasmonic cavity created by an assembly of the first plasmonic surface, the second plasmonic surface, and the dielectric-filled gap, and having a spectrally separated first fundamental resonant cavity wavelength λand second fundamental resonant cavity wavelength λ. The plasmonic apparatus includes a plurality of fluorescent particles located in the dielectric-filled gap. Each fluorescent particle of the plurality of fluorescent particles having an absorption spectrum including the first fundamental resonant cavity wavelength λand an emission spectrum including the second fundamental resonant cavity wavelength λ.
