ZnO nanoparticles obtained by hydrothermal methodat low temperature

摘要

The structural properties and morphology of ZnO nanoparticles obtained by hydrothermal method were studied. ZnOsamples were obtained by hydrothermal method, in soft synthesis conditions, temperature of solution about 70°C, inpresence of a bidentate ligand or a tensioactive agent. The resulted oxides morphologies were compared with themorphologies of ZnO samples obtained in absence of ligands or tensioactive agents. Samples present a hexagonal phaseof ZnO with lattice parameters about a=0.32nm and c=0.5nm, values confirmed by XRD measurements. Morphologicalproperties are studied using bright field images, measuring the nanoparticles diameter and nanopellets size.
