Abstract

Plasmonic effects in metal nanoparticles enhancing near-field light-matter interaction have multiple applications in bright sources and sensing. Gallium (Ga) is an important plasmonic material allowing for flexible electronics with facile room-temperature synthesis and tunable resonances in visible spectrum range. Here, in addition to showing a three-fold near-field plasmonic enhancement observable in Raman spectroscope, we demonstrate a spectrally selective strong Purcell enhancement of the B-exciton series in chemically synthesized MoSe2 flakes.
