摘　　要：采用静电纺丝法制备出了高长径比的立方相In2O3纳米线。将In2O3纳米线置于NH3气流中进行原位氮化反应,合成得到了高质量的InN纳米线,转化率高达100%。通过调节氮化反应的温度及时间,系统研究了制备InN纳米线的最佳合成工艺参数。利用这种方法得到的氮化铟纳米线具有长径比高、直径分布单一、纯度高以及产量大的特点,为今后InN纳米器件的大规模制备和应用提供了一个有效的途径。Cubic-phase In2O3 nanowires with a high aspect ratio were prepared via electrospinning. High-quality InN nanowires with a conversion rate of 100% were synthesized by in situ nitriding of the electrospun In2O3 nanowires in an NH3 flux. By adjusting the temperature and time of nitridation reaction, the optimized parameters were obtained. The as-synthesized InN nanowires have a high aspect ratio, uniform diameter, high purity and high yield, which show great potential for the mass production of InN-based nanodevices.
