Synthesis and Characterization of ZnO Ellipsoid-like Nanostructures

"ZnO ellipsoid-like structures assembled by ZnO nanrods were fabricated from common ZnO whiskers by autoclave tests and pyrolysis integrated method. X-ray diffraction, scanning electron microscopy, transmission electron microscopy, selected area electron diffraction, and high resolution transmission electron microscopy studies reveal ZnO ellipsoidal structures are single-crystals and formed from direct oriented attachment of nanorods. Raman and room temperature photoluminescence spectra are also discussed."
