| 摘 要： | Water-soluble Mn2＋-doped ZnS nanocrystals surface capped with polyethylene glycol（expressed as PEG-ZnS：Mn2＋） were synthesized in aqueous solution with PEG as surface modifier without ligand exchange.The particles were obtained via chemical precipitation method at 100 ℃ with an average diameter of 3 nm and a zinc blende structure.The PEG modified on the surface of PEG-ZnS：Mn2＋ nanocrystals rendered the nanocrystals water soluble and biocompatible.And the PEG-ZnS：Mn2＋ nanocrystals have the potential application in molecular assembly and biological fluorescence analysis.The effects of the Mn2＋ concentration,stabilizer concentration,and synthesis time on the photoluminescence（PL） intensity of ZnS：Mn2＋ QDs were also investigated.
