    • The theoretical PIA is not as broad as in the experimental case,(17) as, being obtained for a single dot and, most importantly, for a single trap state, does not include the broadening effects due to the energy distribution of the different types of traps (see Figure 1), and, to a lesser extent, to size dispersion

    • Out of the three components extracted from the triexponential fit by Patra et al. one (number 2 in Table 1 of ref 18) has a lifetime magnitude compatible with the radiative decay time(35) and an amplitude that follows the observed PL intensity. We therefore attribute it to radiative decay and associate the remaining two components (1 and 3) with the (slow and fast) nonradiative components
