摘要	Novel hierarchical ZnO hexagonal towers were fabricated via chemical vapor deposition for the first time by adding trace Fe power in the precursor as a catalyst. The scanning electron microscopy images showed that the outside surface of novel hierarchical ZnO hexagonal towers was layer-by-layer assembly. X-ray diffraction pattern indicated that the hierarchical ZnO hexagonal towers grew preferentially along the [0001] direction. Intense UV emission centered at 380 nm was observed at room temperature. Moreover, their field-emission properties were studied. A low turn-on electric field of 2.37 V mu m(-1) and high field enhancement factor of about 2691 were obtained, due to the novel layer structure and high crystalline quality. This kind of hierarchical ZnO microstructures could be a good candidate for high performance field emission devices. (C) 2012 Elsevier B.V. All rights reserved.
