  Abstract: We report on microstructural, optical   and magnetic properties of (Zn,Mn)O nanostructures synthesized by   a chemical vapor deposition (CVD) technique. Average diameters of   the as grown (Zn, Mn) O nanorods and nanowires were similar to   400 nm and similar to 50 nm, respectively. X-ray diffraction   (XRD) and photoluminescence (PL) spectra provided the evidence   that Mn was incorporated into ZnO lattice. PL spectra of the (Zn,   Mn) O nanostructures showed shift in near band edge (NBE)   emission at 396 nm together with a green band (GB) emission at   510 nm and a blue band (BB) emission at 460 nm. Magnetic   measurements revealed mixed magnetic phases (ferromagnetic and   antiferromagnetic) in the (Zn, Mn) O nanostructures.   Vapor-solid-solid (VSS) mechanism was thought to be responsible   for the growth of the nanostructures at low temperatures.
