摘要

首先以CdCl

2.5H

O、SeO

和NaBH

为反应物，制备巯基丁二酸稳定的CdSe量子点。然后将有机膨润土与CdSe量子点溶液混合并充分搅拌，制备负载CdSe量子点的膨润土发光材料，用荧光光谱、扫描电镜和X射线粉末衍射等分析测试手段对所得材料的光谱性能与微观结构进行表征。光谱分析表明，量子点膨润土复合材料的发光颜色与量子点溶液非常一致；X射线光电子能谱分析表明，复合后的材料中含有Cd 和 Se两种元素；此外，在量子点膨润土复合材料X射线粉末衍射谱中可见CdSe量子点（111）、（220）及（331）3个晶面的衍射峰，2

=4.3处出现膨润土（001）衍射峰。数据表明，在制备的CdSe量子点膨润土复合材料中，量子点和膨润土的结构都没有改变。

Abstract

Mercaptosuccinic acid capped CdSe quantum dots were prepared in aqueous solution by using SeO

as selenium source and NaBH

as reductant. Then

the CdSe quantum dots bentonite luminescent material was prepared by mixing the CdSe quantum dots solution and organic bentonite under stirring. The obtained sample was characterized by photoluminescence spectra

scanning electron microscopy and X-ray diffraction. The spectra analysis results disclosed that the illuminant color of quantum dots bentonite composites was similar to the corresponding quantum dots solution. The energy-dispersive X-ray spectra demonstrated that Cd and Se elements presented in the composites. X-ray diffraction measurements indicated that the (111)

(220) and (331) diffraction peak of CdSe appeared in quantum dots bentonite composites

and the (001) diffraction peak at 2

=4.3 in the raw bentonite. These results suggest that the preparation of CdSe quantum dots bentonite composites do not change the structures of quantum dots and bentonite.
