利用Na2S溶液沉淀法制得了Mn2+及Cu2+掺杂的ZnS纳米微晶．用X射线衍射测定了微晶的结构及计算了晶粒尺寸．分析了量子尺寸效应造成的光学特性的变化．讨论了ZnS纳米微晶中不同类型发光中心的不同发光行为．
The ZnS nanocrystals doped with Mn2 + and Cu2 + were prepared by Na2S solution precipitation. The structure of the crystallites was measured by X-ray diffraction and the grain size was calculated. The change of optical properties caused by quantum size effect was analyzed. The different luminescence behaviors of different types of luminescent centers in ZnS nanocrystals were discussed.
