ZnO nanowire attracted nanosheets, nanocartridges and hexagonal nanotowers are fabricated by evaporation of ZnS in the presence of trace oxygen under controlled conditions. The nanosheet has an irregular structure, and nanowires sprout from the flange of the nanosheet. The nanocartridge has one row of prismatic nanorods grown on the (0001) surface of the ZnO nanobelts. The hexagonal nanotower, which grows along the c axis, shows an interesting layer structure and seems to form by piling up hexagonal ZnO nanocrystals layer on layer. These nanomaterials might have potential applications in optoelectronics.
