以过硫酸铵为氧化剂，在锌箔衬底上制备了直径和长度均匀、垂直排列的ZnO纳米棒，制备方法简便、规模大、合成成本低，无需添加模板和添加剂。SEM和XRD研究表明，ZnO纳米棒沿c轴取向良好。荧光光谱表明，我们合成的氧化锌纳米棒具有更强和更宽的绿色发射，是纳米光电器件中电子纳米导体的有希望的候选者。此外，通过一种有效的巯基乙酸辅助溶液途径，成功地合成了排列良好的ZnO/ZnS纳米电缆和ZnS纳米管阵列。ZnS纳米管呈完美的六边形和明显的管状。我们目前的策略表现出温和的增长条件和良好的可重复性。
Vertically aligned ZnO nanorods with uniform diameter and length have been synthesized on a zinc foil substrate with ammonium persulfate as oxidant via a facile, larger scale production and inexpensively synthesized method without any templates or additives. SEM and XRD studies indicate that ZnO nanorods are well-oriented along the c-axis. The PL spectrum indicates that our as-synthesized ZnO nanorods with a stronger and wider green emission are promising candidates as electron nanoconductors in nano-optoelectronic devices. Furthermore, by an effective thioglycolic acid-assisted solution route, well-aligned ZnO/ZnS nanocable and ZnS nanotube arrays have been successfully synthesized. ZnS nanotubes show a perfect hexagonal and obvious tubular shape. Our present strategy shows mild growth conditions and good reproducibility.
