Low temperature synthesis, photoluminescence, magnetic properties of the transition metal doped wurtzite ZnS nanowires

摘要

In this paper, we synthesized the transition metal ions (Mn, Cu, Fe) doped and co-doped ZnS nanowires (NWs) by a one-step hydrothermal method. The results showed that the solid solubility of the Fe~(2+) ions in the ZnS NWs was about two times larger than that of the Mn~(2+) or Cu~(2+) ions in the ZnS NWs. There was no phase transformation from hexagonal to cubic even in a large quantity transition metal ions introduced for all the samples. The Mn~(2+)/Cu~(2+)/Fe~(2+) related emission peaks can be observed in the Mn~(2+),Cu~(2+) and Fe~(2+) doped ZnS NWs. The ferromagnetic properties of the co-doped samples were investigated at room temperature.
