Effect of deposition time on the properties of ZnO nanopowder prepared by microwave-assisted hydrothermal synthesis

摘要

In this study, nanoparticule ZnO powders synthesized via microwave-assisted hydrothermal method at different deposition time. The effects of deposition time on structural and morphological properties of nanoparticule ZnO powders. Nanoparticule ZnO powders have polycrystalline structure with (002) preferential orientation. The information on crystallite size were obtained from the fullwidths-at-half-maximum (FWHM) of the diffraction peaks. Surface morphology was studied using a ZEISS Ultraplus model field emission scanning electron microscopy (FESEM).
