Core size and shell thickness dependence of Auger recombination rates. a Illustration of Auger recombination pathways for negative trion (X⁻), positive trion (X⁺), and biexciton (XX), and the relation among three rates. b, c Core size dependence of Auger recombination rates of X⁻ (red) and X⁺ (blue) for CdSe/CdS core/shell quantum dots (QDs) with four and eight monolayers of shells, respectively. d–f Shell thickness dependence of Auger recombination rates of X⁻ (red) and X⁺ (blue) for CdSe/CdS core/shell QDs with the first-exciton absorption peak of core at 550, 590, and 630 nm, respectively. The data for CdSe/CdS core/shell QDs with the first-exciton absorption peak of core at 550 nm and 16 monolayers of shell in d (light blue and light red) is from ref. ²⁵. Error bars are defined as s.d.
