摘　　要：采用六次甲基四铵作为新型缓冲修饰剂合成掺锰硫化锌量子点,并对其进行透射电镜,X射线衍射以及磷光表征。探讨了不同溶剂,不同缓冲体系以及β-环糊精添加剂合成条件下对量子点磷光性能的影响。发现利用合成的掺锰硫化锌量子点的磷光性质可实现对Cu^(2+)选择性检测,检测限为0.2%mol/L。Mn doped ZnS quantum dots were prepared using urotropine as the new buffer modifier firstly,and were characterized by transmission electron microscopic image,X-ray diffraction and phosphorescence. Effects on the quantum dots synthesized by different solvents,buffer solutions and added β-cyclodextrin were also studied with the phosphorescent methods. The studies were found to selectively detect Cu^（2＋）in aqueous solution at 0. 2 %mol/L level of detection.
