Deskripsi
Here, the authors show brightening of dark excitons by strong coupling between cavity photons and high energy, spin-allowed, bright excitons in monolayer WSe2. In this regime, the commonly observed photoluminescence quenching stemming from the fast relaxation to the dark ground state is prevented.
