| ZnO Nanorod Arrays: Synchronous Preparation and PL Performances | |
| 摘要: 在较低温度下，采用化学法在Zn片和玻璃片上同步制备了ZnO纳米棒阵列。利用XRD、FESEM和HRTEM对样品进行了表征，并且通过光致发光谱研究了阵列的光致发光(PL)性能。结果表明，ZnO纳米棒阵列较为致密、取向性较好。纳米棒为六方纤锌矿相，沿c轴生长，平均直径约为60 nm。同步法制备的2种ZnO纳米棒阵列均具有较好的紫外和橙红色发光性能，但发光特性却存在一定差异，这可能主要是由于2种阵列中纳米棒的缺陷含量不同所致。 | |

| Abstract: ZnO nanorod arrays were synchronously prepared on Zn piece and substrate by means of chemical method under low temperature. The ZnO arrays were characterized using XRD， SEM and HRTEM， and the photoluminescence performances of the arrays were principally investigated. The results show that ZnO nanorod arrays are dense and exhibit good orientation. The individual ZnO nanorod grows along with c-axis with size about 60 nm， and the nanorod is with Wurtzite structure. In addition， the ZnO nanorod arrays both on Zn piece and on substrate emit strong ultraviolet， while there are different performances in salmon pink emission， which results possibly from different defect contents in nanorods of two arrays on Zn piece and substrate. | |
