Abstract
Mn-doped ZnO nanostructures with significant room-temperature ferromagnetism have been synthesized at high temperature for the first time using polystyrene (PS) as a template. The X-ray diffraction and transmission electron microscopy analyses of these samples showed the formation of impurity-free crystals with wurtzite ZnO structure. SEM and TEM studies of PS-treated ZnO showed predominantly rod-like microstructure, while PS-treated Zn0.95Mn0.05O showed nearly spherical aggregated particles with a flower-like morphology in the nanometer regime. Quenching of visible emission intensity observed with the doping of Mn ions into ZnO confirmed the changed defect structure in PS-treated Mn-doped ZnO lattice.
