Fig. 2: In-plane magnetic field B//—spin-forbidden dark exciton in MoSe2 monolayer encapsulated in hBN revealed by photoluminescence.
From: Measurement of the spin-forbidden dark excitons in MoS2 and MoSe2 monolayers

a Color map of the variation of the PL intensity as a function of B// (the PL intensity of the bright exciton has been normalized at each field); b energy of dark and bright excitons as a function of B//. The solid lines correspond to the fit described in the text.
