Representative blinking behavior of a molecular emitter and a colloidal nanocrystal quantum dot. a–c A single Alexa 594 dye molecule and d–f individual CdSe/CdS core/shell nanocrystal quantum dot. PL lifetimes extracted from different intensity levels are color-coded to highlighted regions in blinking traces. Molecular blinking is characterized by burst-like emission with nearly uniform distribution of lifetimes across the intensity range. NQD’s blinking shows well-defined emission intensity levels with discrete lifetime values due to radiative recombination in various excitonic complexes. X0—neutral exciton, X− —negatively charged trion, X+—positively charged trion, XX*—multiply charged excitons or charged biexcitons. Bin size is 20 ms
