Fabrication of nanomaterials using photoinduced plasma

我们开发了一种快速高效的纳米材料制备系统，该系统利用超短脉冲激光在玻璃流动反应器中诱导等离子体。利用<14><17>该系统成功地制备了小于理论单磁畴尺寸的Nd_2Fe_ B、Sm_2Fe_ N_3和FePt等永磁纳米粒子。除了基本的理解，我们预计我们的系统将在纳米材料制造，材料加工，光学捕获和生物医学铁磁流体打开新的机会。

We have developed a rapid and highly-efficient nanomaterial production system by using ultrashort pulse laser induced plasma inside a flow reactor made of glass. The permanent magnet nanoparticles such as Nd_2Fe_<14>B, Sm_2Fe_<17>N_3, and FePt, which are smaller than a theoretical single magnetic domain size, were successfully produced by using this system. Beyond the basic understanding, we anticipate that our system will open new opportunities in nanomaterial fabrication, material processing, optical trapping, and bio-medical ferrofluids.
