Query: Photodarkening of blinking quantum dots is not governed by Auger
  recombination   The observed intermittent light emission from colloidal semiconductor
nanocrystals has long been associated with Auger recombination assisted
quenching. We test this view by observing transient emission dynamics of
CdSe/CdS/ZnS semiconductor nanocrystals using time-resolved photon counting.
The size and intensity dependence of the observed decay dynamics are
inconsistent with the those expected from Auger processes. Moreover, the data
suggests that in the `off' state the quantum dot cycles in a three-step
process: photoexcitation, rapid trapping and subsequent slow nonradiative
decay.
