We demonstrated the successful fabrication of MgO-core/ZnO-shell nanowires, in which the shell layers were deposited by using the sputtering technique. Transmission electron microscopy investigations revealed that core nanowires were surrounded by a ZnO shell layer. At 298 K, the photoluminescence (PL) peak intensity ratio (green/UV) decreased with increasing ZnO shell thickness. In regard to the effect of temperature, the intensity of the green emission band was progressively decreased with increasing measurement temperature. We discuss the possible associated PL emission mechanisms.
