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

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。

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
c
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
+2
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.
