By using gold nanorods as an example, we report the dynamic and reversible tuning of the plasmonic property of anisotropically shaped colloidal metal nanostructures by controlling their orientation using external magnetic fields. The magnetic orientational control enables instant and selective excitation of the plasmon modes of AuNRs through the manipulation of the field direction relative to the directions of incidence and polarization of light.
以金纳米棒为例，我们通过使用外部磁场控制其取向，报告了各向异性胶体金属纳米结构的等离子体特性的动态和可逆调谐。通过相对于光的入射和偏振方向操纵场方向，磁定向控制实现了对 AuNRs 的等离子体模式的即时和选择性激发。
