Enhanced Photoluminescence From Quantum Emitter-Nanoplasmonic Antenna Hybridization by a Facile Fabrication Method

Abstract

Gaps between tiny metallic nanostructures create strong local fields and small mode volumes, known as hybrid plasmonic modes. This study introduces a nanocavity formed by silver nanoparticles on a gold substrate with hexagonal boron nitride flakes, boosting quantum emitters' spontaneous emission and photoluminescence yield.
