Experimental and simulated power dependent spectra (normalized). Left: Experimentally obtained normalized PL spectra for different excitation powers. The ratio of these powers is the same as the simulations in the left panel. Right: Simulated evolution of the normalized PL spectra for ratio’s of excitation power identical to that of Figure 2. Inset: Comparison of experimental and simulated peak wavelengths for the different excitation powers.
