主 题：resolution light plasmon
摘 要：The light-matter interaction between plasmonic nanocavity and exciton at the sub-diffraction limit is a central research field in ***,we demonstrated the vertical distribution of the light-matter interactions at~1 nm spatial resolution by coupling A excitons of MoS2 and gap-mode plasmonic ***,we observed the significant photoluminescence(PL)enhancement factor reaching up to 2800 times,which is attributed to the Purcell effect and large local density of states in gap-mode plasmonic ***,the theoretical calculations are well reproduced and support the experimental results.
