Plasmon-modulated photoluminescence of the photoexcited hyperbolic meta-antennas

Abstract

In this work, we performed a systematic study on a hybrid plasmonic system to elucidate a new insight into the mechanisms governing the fluorescent enhancement process. We have used hyperbolic meta-antennas to study the emission properties of CdSe/ZnS quantum dots (QDs). By introducing a dielectric layer inside the plasmonics antenna we engineer the absorption and scattering spectrum. Our lithographically defined meta-antennas with various diameters act as receiver and transmitter nano-antennas to outcouple efficiently the photoluminescence of the QDs.
