论文摘要
元素硼的纳米颗粒是通过激光消融液体异丙醇中的烧结硼靶的激光消融和随后的悬浮液的激光片段化而产生的。为此，使用1060-1070 nm的波长使用ytterbium掺杂的纤维激光器，脉冲重复速率为20 kHz，脉冲持续时间为200 ns。消融后硼纳米颗粒的大小约为30 nm。纳米颗粒主要由硼和碳制成，有些颗粒具有碳壳。纳米颗粒的同素异源组成与初始硼靶的不同。讨论了可能的应用程序。
Nanoparticles of elemental Boron are generated for the first time by laser ablation of a sintered Boron target in liquid isopropanol and subsequent laser fragmentation of the suspension. For this purpose an ytterbium doped fiber laser was used at wavelength of 1060-1070 nm, pulse repetition rate of 20 kHz, and pulse duration of 200 ns. The size of Boron nanoparticles after ablation and fragmentation of the suspension is around 30 nm. Nanoparticles are made mostly of Boron and carbon, some particles have carbon shell. Allotropic composition of nanoparticles differs from that of the initial Boron target. Possible applications are discussed.
