| Summary: | We present a study
of the dilute magnetic and optical properties of
Mn-doped ZnO nanowires (Nws) fabricated by means
of a liquid phase evaporation deposition
process. The samples were grown using a mixed
Zn/Mn liquid source with a mol ratio of Mn
10% in a constant O2/Ar gas at
580°C. The nanowires show a strong UV emission at
405 nm and a blue emission at 433 nm in the
photoluminescence spectrum. In addition, they present a strong
reversible smooth ferromagnetic hysteresis loop at room
temperature, and the corresponding saturation magnetization Ms is up to 0.015 emu/g Oe, showing that the
nanowires are of a ferromagnetism semiconductor (DMS). With the
strong magnetic and photoluminescence properties, ZnO : Mn Nws will
be used in fields of making electromagnetic devices and
magneto-optical storage devices. |
