The well-aligned ZnO nanorods with 5 at.% of Mn doping (Zn0.95Mn0.05O) were deposited on silicon (100) substrates by pulsed laser deposition at three different substrate temperatures ranged from 600 ℃ to 700 ℃, while the structure with and without a ZnO seed layer were both considered. The magnetic and structural properties of Zn0.95Mn0.05O nanorods has been characterized by X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), and superconducting quantum interference device (SQUID). We demonstrate that the distribution and diameter of well-aligned Zn0.95Mn0.05O nanorods are controllable, which strongly depend on the substrate temperature. Also, the magnetic properties are directly controlled by the morphologies of Zn0.95Mn0.05O nanorods, and are thus appropriate for further applications.
