ZnO已成为光子学和光电学研究的热点。我们在不对称管中通过碳的可控还原反应制备了纯Mn（II）掺杂的ZnO纳米线。详细的时间分辨光致发光实验研究表明，不同的ZnO纳米线存在激子-激子相互作用、双极化激子凝聚和等离子体三种激光机制，通过在ZnO纳米线中掺杂Mn可以改变这些机制。详细讨论了各种机制之间的转换及其光谱行为。这些结果对未来紫蓝色发光和显示器件的设计具有重要意义。
ZnO has become the focus of photonics and optoelectronic research. We prepared pure Mn(II) doped ZnO nanowires with a controlled reduction reaction by carbon in an asymmetrical tube. Careful time-resolved photoluminescence experimental study indicates three types of lasing mechanisms: exciton-exciton interaction, bipolaronic exciton condensation, and plasma; these exist in different ZnO nanowires, which can be changed by doping Mn in ZnO nanowire. The transformation between varied mechanisms is discussed in detail with their spectral behaviors. These results are important in the design of future violet-blue luminescence and display devices.
