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。 Hexamethylenetetramine was used as a new buffer modifier to synthesize zinc doping ZnS quantum dots and characterized by transmission electron microscopy, X-ray diffraction and phosphorescence. The effects of different solvents, different buffer systems and β-cyclodextrin additives on the phosphorescence properties of quantum dots were investigated. It was found that the selectivity of Cu2 + could be detected by the phosphorescence of synthesized ZnS doped quantum dots with the detection limit of 0.2% mol / L.
