• Description: This study systematically investigates the effect of solvent isotope exchange (H2O › D2O) on the luminescence behavior of three classes of commercially available QDs: graphene QDs (GQDs), CdTe core-type QDs (C-QDs), and CdSe/ZnS or CdS/ZnS core/shell QDs (CS-QDs). Luminescence intensity, quantum yield (QY), and fluorescence lifetime were measured under identical conditions in both H2O and D2O solvents.This study systematically investigates the effect of solvent isotope exchange (H2O › D2O) on the luminescence behavior of three classes of commercially available QDs: graphene QDs (GQDs), CdTe core-type QDs (C-QDs), and CdSe/ZnS or CdS/ZnS core/shell QDs (CS-QDs).
