Abstract
- Abstract: At low temperature, Mn-doped ZnO mesocrystals have been prepared in a hydrated ionic liquid precursor tetrabutylammonium hydroxide (TBAH). A clear hysteresis with coercive field Hc =85 Oe and remanence Mr =0.0213emug−1 was observed in Zn0.95Mn0.05O mesocrystals, but only paramagnetism was observed in Zn0.95Mn0.05O nanorods. The morphologies, structures, chemical state, optical properties and room temperature ferromagnetic properties of the synthesized Zn0.95Mn0.05O samples could be controlled simply by changing the concentration of zinc acetate in ionic liquid precursor.
