Title: | Ultraviolet laser action in ferromagnetic Zn₁₋ₓFeₓO nanoneedles | Authors: | Yang, HY Yu, SF Lau, SP Herng, TS Tanemura, M |
Issue Date: | 1-Nov-2009 | Source: | Nanoscale research letters, 1 Nov. 2009, v. 5, no. 1, p. 247-251 | 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. | Keywords: | Zn₁₋ₓFeₓO Nanoneedles Ferromagnetic Random lasing Ion beam |
