摘　　要：有效地制备出均一单相的Mn掺杂ZnO基纳米纤维是构建微型自旋电子器件的前提和基础。采用静电纺丝法制备了5种不同浓度的Mn掺杂ZnO纳米纤维。通过调节控制纺丝过程中的工作电压,可以有效控制前驱体纤维的形貌和直径分布。在适当的热处理条件下,XRD图谱表征该5种掺杂浓度的纤维均呈现良好的六方纤锌矿结构。光致发光谱显示该纤维在400~1000nm的波长范围内出现了2个发光峰,且均随着Mn掺杂的进入而发生蓝移现象。The preparation of uniform single-phase Mn-doped ZnO nanofibers lays the foundation for constructing micro-spin-electronic devices. An electrospinning method was adopted to fabricate 5 kinds of Mn-doped ZnO nanofibers with different doping concentrations. The morphology and diameter distribution of as-prepared fibers before calcination could be controlled by varying applied voltage. XRD patterns demonstrate that all the 5 samples are of single wurtzite structure. PL spectra show that there are 2 light-emitting peaks within the spectrum range from 400 nm to 1000 nm and they both have a blue-shift as Mn element is doped into ZnO.
