我们报道了由无机多层膜结构支持的布洛赫表面波与有机半导体中J-聚集态激子之间的强耦合。通过角分辨衰减全反射和光致发光实验研究了所产生的极化激元模式的色散曲线。实验测得的拉比分裂为290 meV。这些结果与我们的理论模型得到的结果是一致的。(C)2014 AIP Publishing LLC.
We report on the strong coupling between the Bloch surface wave supported by an inorganic multilayer structure and J-aggregate excitons in an organic semiconductor. The dispersion curves of the resulting polariton modes are investigated by means of angle-resolved attenuated total reflectance, as well as photoluminescence experiments. The measured Rabi splitting is 290meV. These results are in good agreement with those obtained from our theoretical model. (C) 2014 AIP Publishing LLC.
