Abstract Thioglycolic acid and mercaptopropionic acid capped water-soluble CdTe quantum dots(QDs) were synthesized via hydrothermal process. The interaction between CdTe QDs and Pb2+ were investigated by fluorescence spectroscopic approaches. The results showed that the fluorescence of CdTe QDs could be irreversibly quenched by Pb2+. According to Stern-Volmer and double logarithm regression curve, the mechanism was discussed. The results showed that the intensity of CdTe QDs could be quenched by Pb2+ significantly, the quenching mechanism was intrinsic fluorescence of static quenching.
