    • The increased nonradiative rate is proposed to occur in an efficient Auger-like process where the exciton energy is transferred to the unpaired charge. The unpaired charge is excited to higher electronic states and then is ejected from the QD, or if the barrier is sufficient, simply thermalizes to the ground state. Chepic et al. (Ref. 41) postulated this effect to explain the observations that for semiconductor QDs embedded in glasses, strong illumination with light to the blue of the band edge caused photodarkening and a large increase in the nonradiative rate that was reversible upon heating. The photodarkening was attributed to ionization of the QDs (see V. J. Grabovskis et. al Fiz Tverd. Tela (Leningrad) 31 (1989) [Sov. Phys. Solid State 31, 272 (1989)]).
