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.
