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
