Summary

Memory effects in single nanocrystal fluorescence blinking are linked to charge trapping kinetics. A fluctuation-based mechanism causes power-law distributions and memory, while ionization-induced trapping reduces memory effects.

Memory effects decrease with earlier crossover times and smaller power law coefficients.

A link between memory effects and blinking kinetics is established.

Conclusions:

Two competing charge trapping mechanisms govern blinking.
Fluctuation-based trapping causes power-law distributions and memory.
Ionization-induced trapping leads to crossover and reduced memory.
