Abstract | Co-doped ZnO single-crystalline nanorods with 80-100 nm in diameter and 1.5-2 mu m in length have been prepared in a simple solution route. X-ray diffraction data and selected area electron diffraction pattern of the diluted magnetic semiconductor nanorods confirm the single crystallinity of Zn(1-x)Co(x)O solid solution without impurities of metallic Co or other phases. Magnetic results show that the Zn(0.95)Co(0.05)O nanorods exhibit a ferromagnetic characteristic with Curie temperature higher than 380 K. The high-temperature ferromagnetic properties allow this Zn(1-x)Co(x)O nanorods potential applications in future spintronic devices. (C) 2008 Elsevier B.V. All rights reserved. |
