摘要

由于有效的激子自捕获，TDBC j聚集体在层状聚合物薄膜中显示出非常小的荧光量子产率为0.5 %。我们发现，利用荧光等离子体增强效应，TDBC j聚集体的荧光可以在一定距离上与金纳米粒子相互作用，使其荧光增加两倍以上。

Plasmon-Enhanced Fluorescence of Carbocyanine J-Aggregates in Layered Polymer Films

TDBC J-aggregates reveal a very small fluorescence quantum yield of $\sim 0.5$% in layered polymeric films due to effective exciton self-trapping. We showed that by using an effect of fluorescence plasmon-enhancement, it is possible to increase the TDBC J-aggregate fluorescence more than two times due to their interaction with gold nanoparticles at a certain distance.
