摘要：

One-dimensional ZnO nanoshuttles were synthesized on Si substrates by a hydrothermal method at 90°C for 24 h using hexamethyenetetramine(HMT) and zinc nitrate as raw materials. The morphology and crystal structure were characterized by field-emission scanning electron microscopy, X-ray diffraction, and high resolution transmission electron microscope. All the data indicated that ZnO nanoshuttles are homogeneous in morphology and uniform in size, with a single-crystal hexagonal wurtzite structure and acceptable crystal quality. Room-temperature photoluminescent spectra showed that a strong near-bang-edge UV emission peak and a much weak defect emission, which suggested that ZnO nanoshuttles have a good optical quality. The nucleation and growth mechanism in the reaction process of ZnO nanoshuttles were also discussed in this work.
