Abstract:

Two-dimensional single-crystalline ZnO nanosheets have been successfully synthesized in high yield from a mixture of ZnO and graphite powders via a microwave thermal vapor process. Morphological analysis indicates that the widths and thickness of the nanosheets are in the range of several to tens of m and 20–80 nm, respectively. ZnO nanosheets grew along the [0001] and 2110 directions, and the width-to-thickness ratio of the nanosheets could reach up to 1,000. The room temperature photoluminescence revealed that the ZnO nanosheets exhibited a weak ultraviolet (UV) emission at ∼378 nm and a strong green emission at ∼505 nm.
