Anti-Stokes Photoluminescence in Monolayer WSe${}_2$ Activated by Plasmonic Cavities through Resonant Excitation of Dark Excitons

Niclas S. Mueller, Rakesh Arul, Ashley P. Saunders +9

Anti-Stokes photoluminescence (PL) is light emission at a higher photon energy than the excitation, with applications in optical cooling, bioimaging, lasing, and quantum optics. He…
