Ultraviolet laser action in ferromagnetic Zn1-xFexO nanoneedles. Nanoscale Research Letters, 5(1), 247-251. | Series/Report no.: | Nanoscale research letters | Abstract: | Fe-doped ZnO nanoneedles (NDs) were fabricated by an Ar+ ion sputtering technique operated at room temperature. The as-grown samples show both ferromagnetic and lasing properties. The saturated magnetization moment was measured from 0.307 to 0.659 emu cm-3 at the field of 10 kOe with various Fe concentrations. Intense ultraviolet random lasing emission was observed from Zn1 - xFexO NDs at room temperature. The X-ray photoelectron spectroscopy result reveals that the doped Fe atoms occupy the Zn sites and lead to a decrease in oxygen deficiency. | URI: | https://hdl.handle.net/10356/84781 http://hdl.handle.net/10220/6271 |
