(a) PL spectrum series measured over 22 min laser illumination showing the evolution of the PL spectrum over time \({I}_{L}=6 kW{cm}^{-2}\), \({t}_{i}=1 s\). (b) Diagram illustrating model used to describe dynamics of excited state populations, corresponding with Eqs. (1–5) (c) Fitted spectra weightings of exciton (X0), charged exciton (CX), and localised exciton (LX) emission (plotted as circles) compared with simulated data (plotted with lines) obtained using the proposed model. Error bars are estimated to be smaller than the data points, more on this can be found in the supplementary materials.
