以Zn0.97Co0.03S(en)0.5为前驱体，通过热分解合成了由单晶Co:ZnS芯和多晶Co:ZnO壳组成的Co:ZnS/Co:ZnO核壳纳米结构。Co:ZnS/Co:ZnO核壳纳米结构将优异的可见光致发光和室温铁磁性集成到一个纳米材料中。与Co:ZnS纳米棒相比，Co:ZnS/Co:ZnO核壳纳米结构由于形成Co:ZnO壳引入了大量的界面缺陷，其光致发光性能和铁磁性得到了显著提高。
Co:ZnS/Co:ZnO core–shell nanostructure, which consists of single-crystalline Co:ZnS core and polycrystalline Co:ZnO shell, has been synthesized via thermal decomposition of Zn0.97Co0.03S(en)0.5precursor. The Co:ZnS/Co:ZnO core–shell nanostructure integrates outstanding visible photoluminescence and room-temperature ferromagnetism into one nanomaterial. Compared to Co:ZnS nanorods, the photoluminescence and ferromagnetism of the Co:ZnS/Co:ZnO core–shell nanostructures are significantly improved due to the introduction of large amount of interfacial defects by forming Co:ZnO shell.
