Extended Data Fig. 7: Stern–Volmer study for the mixture of CdTe QDs and cysteine.

Extended Data Fig. 7

The ratios of PL emission intensities of CdTe QDs (I0/I) without and with the addition of different equivalents of cysteine (Cys). A linear relationship was observed at low Cys equivalents, demonstrating a dynamic quenching mechanism orientated from the diffusive encounters between the Cys molecules and the emissive QDs. The saturated values of I0/I under high Cys equivalents due to quencher accessibility are consistent with the literature report64.
