采用金属有机化学气相沉积的方法，将直径为20 nm的胶体金纳米颗粒分散在SiO_2/Si衬底上，制备了直径为20~60 nm、长度为5~15µm的氧化锌纳米线。光致发光测试表明，所制备的氧化锌纳米线具有很高的内部量子效率和可以忽略不计的微弱深能级发射。自由激子和双激子发射的清晰观察表明，用这种方法制备的氧化锌纳米线质量很高。(C)2005年美国物理研究所。
ZnO nanowires with diameters ranging front 20 to 60 nm and lengths in the range 5-15 mu m were synthesized by metalorganic chemical vapor deposition, assisted by colloidal gold nanoparticles with a diameter of 20 nm dispersed on SiO2/Si subsrates. The ZnO nanowires were found to have a high-internal quantum efficiency and negligibly weak deep-level emission, as evidenced by photoluminescence measurements. The clear observation of free-exciton and biexciton emission indicates that the ZnO nanowires prepared by this method are of high quality. (C) 2005 American Institute of Physics.
