摘要

TDBC J-aggregates reveal a very small fluorescence quantum yield of ~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.
