Hybrid nanostructures, such as those with nanoparticles anchored on the surface of nanowires, or decorated nanowires, have a large number of potential and tested applications such as: gas sensing, catalysis, plasmonic waveguides, supercapacitors and more. The downside of these nanostructures is their production. Generally, multi-step synthesis procedures are used, with the nanowires and the nanoparticles typically produced separately and then integrated. The few existent single-step methods are lengthy or necessitate highly dedicated setups. In this paper we report a single-step and rapid (ca. 1 min) laser ablation synthesis method which produces a wide variety of boron-rich decorated nanowires. Furthermore, the method is carried at room temperature. The synthesis process consists on a filamentary jet ejection process driven by pressure gradients generated by the ablation plume on the rims of the irradiation crater. Simultaneously nanoparticles are nucleated and deposited on the filaments thus producing hybrid decorated nanowires.

通过激光烧蚀在室温下一步合成金属装饰的富硼纳米线。

杂化纳米结构，例如那些将纳米颗粒固定在纳米线或装饰的纳米线上的纳米结构，具有大量的潜力和经过测试的应用，例如：气体传感，催化，等离激元波导，超级电容器等。这些纳米结构的缺点是其生产。通常，使用多步骤合成程序，其中纳米线和纳米颗粒通常分开生产然后整合。现有的几种单步方法冗长或需要高度专用的设置。在本文中，我们报告了一种单步，快速（约1分钟）的激光烧蚀合成方法，该方法可产生各种各样的富硼装饰纳米线。此外，该方法在室温下进行。合成过程包括一个丝状射流的喷射过程，该过程由辐照坑边缘上的消融羽流产生的压力梯度驱动。同时使纳米颗粒成核并沉积在细丝上，从而产生杂化装饰的纳米线。
