We have studied the crystallographic structure, morphology and optical properties zinc oxide of two different nanostructures - the 1 D ZnO nanowires (NWs) and the 3 D hedgehog-like ZnO nanostructures. The presence of the nucleation layer was necessary, for the synthesis of 1D ZnO NWs, unlike the preparation of 3D hedgehog-like structures. The crystal structure and morphology of the as-obtained products were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy. The electron paramagnetic resonance (EPR) technique was applied to study paramagnetic defects in nanostructures.
