We report the facile synthesis of gold–silver (Au–Ag) nanostructures in a niche hybrid form of ultrathin wire–dots, where the ultrathin nanowires are embedded with quasi-spherical dots along the longitudinal direction. The key to the success of this work relies on the use of seeded growth and the introduction of excessive Ag ions in the growth stage to facilitate the formation of such a unique architecture. Several reaction parameters, including the amount of silver and reductant, seed quantity and size/morphology, are systematically investigated to reveal their role in determining the morphology of the final products. We also recorded their UV-vis extinction spectra and compared them with pure ultrathin wires to investigate the effect of dot regions on the optical properties.

金-银超薄线-点杂化纳米结构的种子生长

我们报告了以超细丝点的小生境混合形式轻松合成金-银（Au-Ag）纳米结构的情况，其中，超细纳米线在纵向上嵌入有准球形的点。这项工作成功的关键取决于种子生长的使用以及在生长阶段引入过量的银离子以促进这种独特结构的形成。系统地研究了几个反应参数，包括银和还原剂的量，种子数量和大小/形态，以揭示它们在确定最终产物形态中的作用。我们还记录了它们的UV-vis消光光谱，并将它们与纯超细电线进行比较，以研究点区域对光学性能的影响。
