High purity Fe 2 O 3 /ZnO nanocomposites were annealed in air at different temperatures between 100 and 1200°C to get Fe-doped ZnO nanocrystals. The structure and grain size of the Fe 2 O 3 /ZnO nanocomposites were investigated by X-ray diffraction 2θ scans. Annealing induces an increase of the grain size from 25 to 195nm and appearance of franklinite phase of ZnFe...
