Recently, diluted magnetic semiconductors (DMS) have generated widespread interest due to their potential applications for spintronic devices. Mn-doped ZnO is one of the most promising diluted magnetic semiconductors materials due to its room temperature ferromagnetism. In this study, ZnO layer was conformally deposited on the surface of polystyrene (PS) nanoshpere with different diameter (100nm~800nm) by atomic layer deposition (ALD). Then the Zn1-xMnxO (0 < x < 0.1) coatings were grown on ZnO hollow nanospheres by pulsed laser deposition(PLD). According to the results of high-resolution x-ray diffraction, Mn-doping does not change the wurtzite structure of ZnO and the Zn1-xMnxO hollow nanospheres are polycrystalline. Photoluminescence spectra and transmittance show an increase of the band gap with the increasing Mn ion concentration. The magneto-optical properties of the Zn1-xMnxO / ZnO hollow nanospheres were measured by micro-MOKE spectroscopy and strongly depend on the Mn composition fraction.
