Ultraviolet Laser Action in Ferromagnetic Zn(1−x)Fe(x)O Nanoneedles

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...

Sumario: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 − x)Fe(x)O 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.
