Uniform and ultralong single-crystalline tellurium (Te) nanowires with a diameter of 20 nm and length of tens of micrometers can be rapidly synthesized by a microwave-assisted method. The formation process of high-quality Te nanowires is strongly dependent on the reaction conditions such as the amount of polyvinylpyrrolidone (PVP), pH value of initial solution, reaction time, and the choice of surfactant. The hydrophilic Te nanowires display a broadened luminescent emission from shortwave ultraviolet to visible region excited by vacuum-ultraviolet (VUV) under synchrotron radiation at room temperature. Based on the examination of the chemical stability of the as-prepared Te nanowires stored in water, the relationship between the synthetic methodology and chemical stability of Te nanostructures has been discussed.
通过微波辅助法可以快速合成直径为 20nm、长度达数十微米的均匀、超长的碲（Te）单晶纳米线。高质量 Te 纳米线的形成过程强烈依赖于反应条件，如聚乙烯吡咯烷酮（PVP）的用量、初始溶液的 pH 值、反应时间以及表面活性剂的选择。在室温下，利用同步辐射的真空紫外光（VUV）激发，具有亲水性的 Te 纳米线在从短波紫外到可见区域显示出宽的发光发射。基于对制备的 Te 纳米线在水中储存的化学稳定性的检查，讨论了合成方法与 Te 纳米结构的化学稳定性之间的关系。
