Cover Story: In tungsten-based semiconducting transition metal dichalcogenides, the recombination of lower energy electron–hole optical excitations does not lead to photon emissions, because they correspond to transitions that are forbidden either by spin or momentum selection rules. However, these dark transitions can be brightened via scattering with defects or phonons. We find that strong exciton–phonon coupling yields the brightening of dark transitions up to sixth-order phonon replicas. Although defects play a critical role in the brightening pathways of dark excitons and their phonon replicas, these emissions are intrinsic to the material and independent of substrate, encapsulation, growth method, and transfer approach.
