Fig. 2: Low-temperature magneto-photoluminescence spectra of PEPI and Mn:PEPI.

a,c circularly polarized emission spectra at 4 K of the bright and dark exciton (XB and XD, respectively) with continuous-wave excitation at 395 nm. Measurements were performed in Faraday geometry with B = 14 T, corresponding to σ+ detection. Insets: relative intensity change for bright and dark exciton. b,d normalized circularly polarized transient PL kinetics of the dark exciton from 0 T to 14 T, for PEPI and Mn:PEPI, respectively. Dashed lines are bi-exponential fits (see Fig. S5 for details of the fitting procedure). Insets: PL emission rate from the long lifetime component of the fit.
