我们通过角调谐证明了自立纳米棒中局域表面等离子体模式与分子j聚集体层中的激子之间的强耦合。增强的激子-等离子体耦合在与杂化态形成相关的微分反射光谱中产生了类似法诺的线形，导致上下极化子的抗交叉，Rabi频率为125 meV。在强耦合作用下，在光致发光中发现了法诺样线形的重建，表明发射光谱轮廓发生了变化。(C) 2016 AIP出版有限责任公司
We demonstrate here a strong coupling between localized surface plasmon modes in self-standing nanorods with excitons in a molecular J-aggregate layer through angular tuning. The enhanced exciton-plasmon coupling creates a Fano like line shape in the differential reflection spectra associated with the formation of hybrid states, leading to anti-crossing of the upper and lower polaritons with a Rabi frequency of 125 meV. The recreation of a Fano like line shape was found in photoluminescence demonstrating changes in the emission spectral profile under strong coupling. (C) 2016 AIP Publishing LLC.
