研究了以3-巯基丙酸为稳定剂合成水溶性掺锰硫化锌纳米晶的方法。与通常的共沉淀法相比，锌离子与甲基亚胺的配位有助于有效地掺杂锰，从而使该过程具有重现性。为了获得高发光强度，进行后备处理。研究发现，纳米晶的表面状态，如对氧的吸附和对甲基亚胺的配位，对发光强度的增强起着重要的作用。
The synthesis of water-soluble Mn doped ZnS nanocrystals with MPA (3-mercaptopropionic acid) as stabilizer is described. The coordination of Zn ion with MPA helps efficient doping of Mn and thus makes the process reproducible as compared to the common co-precipitation method. To obtain a high luminescent intensity, post-preparative treatments are performed. It is found that the surface states of the nanocrystals, such as the adsorption of oxygen and the coordination of MPA, play important roles in the enhancement of the luminescent intensity.
