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 Zn 1 - xFe xO 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. © 2009 to the authors.
