摘要

以Zn(NO

)

O和CO(NH

)

为原料

采用均匀沉淀法

制备出了棒状、花状、球状纳米氧化锌(ZnO)。将ZnO微球体分散在Na

S溶液中

通过离子替代法

成功制备了ZnO/ZnS核壳结构。利用X射线衍射仪(XRD)、扫描电子显微镜(SEM)、能谱仪(EDS)等测试手段对ZnO纳米结构和ZnO/ZnS核壳结构的晶体结构和表面形貌进行了表征

初步探讨了纳米ZnO和ZnO/ZnS核壳结构的生长机理。根据测试结果得知

ZnO纳米棒呈现六方纤锌矿结构

随着Zn

浓度逐渐增加

ZnO纳米结构形貌由单分散的棒状聚集成花状

最后演变成球形。ZnO/ ZnS复合结构为内核ZnO

外面包覆一层ZnS的核壳结构。所有的纳米ZnO均具有相似的发光特点

ZnO/ZnS核壳结构的发光性能有了很大的改善。

Abstract

Rod-like

flower-like and sphere-like ZnO were prepared by homogeneous precipitation method with Zn(NO

)

O and urea as reactive materials. The ZnO/ZnS core/shell structure was formed through sulfuration conversion from ZnO microspheres in the Na

S solution. The crystal structure and morphology of the as-synthesized samples were investigated by means of X- ray diffraction(XRD)

scanning electron microscope(SEM) and energy dispersive X-ray spectroscopy (EDS). The results show that the as-synthesized ZnO crystals are hexagonal wurtzite structure. SEM images indicated that ZnO hexagonal nanorods grew along

axis and the growth mechanism of ZnO nanorods was discussed. At low Zn

concentration

the morphology of the ZnO nanostructure is flower-like collection assembled from rod-like dispersed single crystals. With the increasing of Zn

concentration

the morphology of ZnO nanostructure changed into spherical collection. The core/shell structure is composed of both ZnO and ZnS. All the products of ZnO nanocrystals exhibited similar photoluminescence characteristics

while the core/shell structure showed an improved emission feature.
