Abstract

Localized photoluminescence manipulation of 1L-MoS2 is achieved by using single shape-controlled Ag nanoantenna. By varying the antenna morphology, the photoluminescence of 1L-MoS2 is continuously tunable from enhanced (>2-fold) to weakened (>2-fold) states. A heterogeneous optical platform is realized by depositing various antennas on the same 1L-MoS2 , with an unprecedented range of photoluminescence output being observed simultaneously.
