采用离子注入技术研究了Co掺杂的晶态氧化锌的结构、磁性和光学性质。光致发光测试表明，随着Co掺杂浓度的增加，注入样品的绿光发射中心从510 nm逐渐移动到531 nm。所有注入样品在室温下都是铁磁性的，饱和磁化强度从6.89×10−5到2.31×10−4emu。对观察到的铁磁性的可能机制进行了讨论。
The ion implantation technique was employed to study the structural, magnetic, and optical properties of Co-doped crystalline ZnO. The photoluminescence measurements indicated that the center of green emission of implanted samples shifts gradually from 510 nm to 531 nm with an increase of Co concentrations. All implanted samples are ferromagnetic at room temperature with a saturation magnetization from 6.89×10−5to 2.31×10−4emu. The possible mechanisms on the observed ferromagnetism were discussed.
