摘要: Nanosized Mn-doped ZnO particles were synthesized using a vapour phase growth method. The x-ray analysis reveals wurtzite structure with small expansion of the lattice constants due to doping Mn in ZnO. TEM shows that nanoparticles have an average diameter around 37 nm, and energy dispersive spectroscopy detection on single nanoparticle indicates manganese concentration is 3.5 at.%. Magnetization measurements under field cooling conditions reveal as-grown show paramagnetic behaviour. This work demonstrates can be doped into nanosized structures via growth, which represents important step towards synthesis diluted magnetic semiconductors.
