- In this work we present the results on the synthesis of zinc oxide nanostructured powders pure and doped with Al by different methods: hydrolysis, hydrothermal and physical vapor deposition in solar reactor. The fine nanostructural characterization of all powders has been performed by X-ray diffraction, SEM electron microscopy and BET analysis. From X-ray diffraction spectra performed on the nanopowders obtained the lattice parameters and the phase changes as well as the average grain sizes and the grain shape anisotropies have been determined. These results are supported by micrographics obtained by SEM. The results show that by combining the hydrothermal synthesis and the solar PVD method it is possible to obtain ZnO nanophases with controlled composition and morphology (from flower-like structure to nanowhiskers).
