Excitation power dependence of emission-peak positions. The emission peak positions of the nanodisc (ND) samples are plotted for excitation powers between 0.035 and 500 µW (measurement errors smaller than data point symbols). The total emission energy shift between the lowest (min) and highest (max) excitation power is given on the right, vertical axis (blue) representing the achieved polarization field screening by excited charge carriers for the QCSE regime and the effect of ND-band filling for the confinement regime
