摘要
We report our laser-driven method used to make large quantities of straight thin silver nanowires, and experimentally demonstrate that femtosecond laser pulse polarization has a prominent effect on formation of non-spherical shapes of nanoscale particles. Further, our experiment directly reveals that the underlying mechanism is ptasmon- plasmon interaction, which can be controlled by poIarization and plays a decisive role in this non-synthetic method for metal nanowire formation.
