Sb-doped ZnO nanoribbons have been synthesized by simple thermal evaporation of powder mixtures of Zn and Sb2O3. The Sb-doped ZnO nanoribbons with hexagonal wurtzite structure have a growth direction of [0110], widths of 100-300 nm, and lengths up to several hundreds of micrometers. The atomic ratio of Sb and Zn is about 1:40 by energy dispersive X-ray spectroscopy measurement. A stripe contrast is found in the center of the Sb-doped ZnO nanoribbon, which is speculated to be due to the enrichment of Sb in the center of the Sb-doped ZnO nanoribbon by energy dispersive X-ray spectroscopy line scanning element mapping. Furthermore, a novel Zn7Sb2O12 branched ZnO nanoribbon structure is investigated. The growth direction of the branch and the backbone are [211] and [0110], respectively. The mechanisms of formation of such nanomaterials are also discussed.
通过简单热蒸发锌和三氧化二锑的粉末混合物合成了锑掺杂的氧化锌纳米带。具有六方纤锌矿结构的锑掺杂氧化锌纳米带的生长方向为[0110]，宽度为100 - 300纳米，长度可达数百微米。通过能量色散X射线光谱测量，锑与锌的原子比约为1:40。在锑掺杂的氧化锌纳米带中心发现条纹对比度，通过能量色散X射线光谱线扫描元素映射推测这是由于锑在锑掺杂的氧化锌纳米带中心富集所致。此外，还研究了一种新型的Zn7Sb2O12分支氧化锌纳米带结构。分支和主干的生长方向分别为[211]和[0110]。还讨论了此类纳米材料的形成机制。
