Fabrication, optical and magnetic properties of the Fe doped Zn_(0.99)Mn_(0.01)S nanowires

摘要

The wurtzite Fe~(2+) doped Zn_(0.99)Mn_(0.01)S nanowires were synthesized by a simple hydrothermal process. The maximum concentration of the Fe~(2+) ions in the Zn_(0.99)Mn_(0.01)S nanowires was 7 %. The average diameter of the samples was in the range of 10-12 nm. The ZnS:Mn~(2+) nanowires exhibited the Mn~(2+) ~4T_（1-）~6A_1 transition centered at 2.1 eV, while the ZnS:Mn~(2+)Fe~(2+) nanowires exhibited the Fe2+ related transition centered at 2.55 eV. Moreover, the ZnS:Mn~(2+)Fe~(2+) nanowires showed the room temperature ferromagnetism property, which can be attributed to the hybridization between the Fe's, Mn's d shell and the S's p shell.
