Anti-Stokes Photoluminescence in Monolayer WSe 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…
