PL lifetime modulation of CdSe/Cds-type QDs by charged ligands and traps. (a) Scheme of 65 and 66. Ligand of 65 with cadmium-carboxylates (with a small amount of negatively charged carboxylates). Ligand of probe 45 with primary amines. (b) Absorption and PL spectra of 65 and 66. (c) PL lifetime of 65 and 66. (d) Scheme of three types of QDs with three monolayers of ZnS outer shells. (e–g) PL spectra of three types of QDs before (black) and after (red) transfer from toluene to water. (a–c) Reprinted with permission from ref (53). Copyright 2020, Nature.
