MoS(2) with Stable Photoluminescence Enhancement under Stretching via Plasmonic Surface Lattice Resonance

In this study, by combining a large-area MoS(2) monolayer with silver plasmonic nanostructures in a deformable polydimethylsiloxane substrate, we theoretically and experimentally studied the photoluminescence (PL) enhancement of MoS(2) by surface lattice resonance (SLR) modes of different silver plasmonic nanostructures. We also observed the stable PL enhancement of MoS(2) by silver nanodisc arrays under differently applied stretching strains, caused by the mechanical holding effect of the MoS(2) monolayer. We believe the results presented herein can guarantee the possibility of stably enhancing the light emission of transition metal dichalcogenides using SLR modes in a deformable platform.
