aμPL spectra of the QD exciton of the uncalibrated sample at 6.0 K with the exciton (X) line and the cavity mode (CM) line. bμPL spectra of the QD exciton of the calibrated sample at 6.0 K. Colored lines: Lorentz fitting of the experimental data. c Time-resolved measurements of uncalibrated sample and the calibrated sample at 6.0 K. d Excitation power-dependent μPL spectra of the uncalibrated sample at 6.0 K; inset: integrated PL intensity of X and CM as a function of excitation power in a log-log scale
