We demonstrate that the correct extension of the arguments used in this analysis provides clear evidence for the existence of a common radiative center associated with a molecule-like species bound to the surface of the PS framework. The results obtained in this study are thus not consistent with quantum confinement and suggest a surface bound emitter as the source of the PS photoluminescence.
