| 英文摘要 | A new method was applied to prepare gan nanorods. in this method, gallium oxide (ga2o3) gel was firstly formed by a sol-gel processing using gallium ethanol, ga(oc2h5)(3), as a new precursor. gan nanorods were successfully synthesized after annealing of the ga2o3 gel at 1000 degrees c for 20 min in flowing ammonia. the as-prepared nanorods were confirmed as single crystalline gan with wurtzite structure by x-ray diffraction (xrd), selected-area electron diffraction (saed) and high-resolution transmission electron microscopy (hrtem). transmission electron microscopy (tem) displayed that the gan nanorods were straight and smooth, with diameters ranging from 200 nm to 1.8 mu m and lengths typically up to several tens of microns. when excited by 280 nm light at room temperature, the gan nanorods had a strong ultraviolet luminescence peak located at 369 nm and a blue luminescence peak located at 462 nm, attributed to gan band-edge emission and the existence of the defects or surface states, respectively.
