摘要	Water-soluble CdTe/CdS core-shell quantum dots (QDs) with the different shell thickness capped with 3-mercaptopropionic acid were synthesized following the synthetic method of successive ion layer adsorption and reaction. UV-Vis absorption spectroscopy, photoluminescence(PL) spectroscopy, transmission electron microscopy(TEM) and time-resolved luminescence were employed to analyze optical characters of QDs. The CdTe/CdS QDs exhibited a significant red shift of emission peak, FWHM increasing and PL lifetime lengthening when the shell layer grew. The experiments revealed that the CdTe/CdS QDs evolve from type- I to type- II core-shell structure with the increase of the shell thickness. The lack of PL lifetime lengthening and quantum yield increasing was ascribed to the surface influence of the shell.
