    • Room-temperature PLE was also performed on the X-2LO emission peak near the band edge, and the excitation profile was virtually identical to that shown in Fig. , except the "enhancement" at 3.26 eV was not as pronounced

    • For moderate-strong exciton-phonon coupling, free exciton luminescence (X-0LO ) is expected to be Gaussian in shape and redshifted from the exciton resonance EX by σ2 / kB T∼ kB T, where σ∼ kB T is the width of the Gaussian line shape (Ref.). For m>0, the peak position of X-mLO luminescence is expected to be at ω X-mLO max = EX -mωLO + (p+1/2 ) kB T, where p=1 for m=1 and p=0 for m>1 (Refs.)
