Spectrally resolved fluorescence decay measurements reveal a non-Auger like dependence of the photoluminescence decay rate with excitation density. Our results suggest that Auger recombination accelerates phonon assisted ionisation that lead to the formation of dark, non-emissive nanocrystal states.
