Abstract

Zn _1-xCo _xO (x=0-0.12) nanowires have been synthesized by the electrophoretic deposition method using anodic aluminum oxide (AAO) as a template. Careful structural characterization indicates that the prepared nanowires are of poly-crystal wurtzite structure and composed with 10-20 nm nano-crystals. Magnetic investigation indicates the obtained nanowires are of room-temperature ferromagnetic. The magnetism increases with the increasing of Co-doping within the solubility limit 7%, but decreases sharply when x>7% for the presence of second-phase Co ₃O ₄. Tubular structural Zn _1-xCo _xO can also be fabricated by properly tuning the electrophoretic deposition potential and time. The mechanism of electrophoretic deposition is discussed in detail.
