| 摘 要： | 通过化学气相沉积(CVD)方法在Si(100)衬底上制备出新型的ZnO纳米钉结构.X射线衍射(XRD)结果表明纳米钉是六角纤锌矿结构.纳米钉顶部对角线在450～750 nm之间,纳米钉长度为几个微米.研究了不同气氛下退火样品的可见发光性质,认为绿光发射来自于导带电子和反位氧中空穴的辐射复合.

| Abstract: | A novel ZnO nanospikes were synthesized on Si(100) substrate by chemical vapor deposition(CVD).X-ray diffraction pattern indicates that the crystal structure of ZnO nanospikes is wurtzite.The caps of the nanospikes are about 450-750nm in diameter and the nanospikes are several microns in length.The change in photoluminescence with annealing condition confirms that green emission originates from the recombination of electrons in conduction band and holes in antisite oxygen defects. |
