摘要: The epitaxial growth of ZnO nanosheets and nanoneedles from a Zn/ZnO core/shell structure is verified by an experiment in which the are synthesized air within ultra-low temperature range from 250 to 400 °C thermal oxidation Zn films made up hexagonal nanodiscs or nanoprisms. structures oxidized form with relationship; found grow epitaxially shell, along sixfold symmetric directions, showing same lattice orientation as core. stability difference among different facets crystal plays key role formation nanosheets, structure, well hollow structures. A vapor–solid mechanism suggested explain process products. Photoluminescence properties nanostructures also explored.
