In this work, a feasible method was proposed to prepare MoS2-based plasmonic hybrid systems with high photoluminescence (PL) emission enhancement. The enhancement effect of hybrids on the PL MoS2 has been systematically studied MoS2/Ag spherical nanoparticle (SP) different architectures by changing stacking position Ag SPs. It is demonstrated that sandwich-like composed monolayer and dielectric Al2O3 layer between two layers SPs highest Remarkably, after adding an under MoS2, intensity up...
Exciton polaritons formed by the strong coupling between excitons and photons have been extensively studied in transition metal disulfides (TMDs) for their potential to inherit ultralong radiation lifetime remarkable nonlinearity. Many studies achieved at room temperature. However, systems these generally lack orderly characteristics precise controllability, tunability also remains rather limited. Here, we demonstrate a plasmonic grating with bound state continuum (BIC) as highly tunable...
Writing spatial information on ultrafast all-optical switching is essential for constructing processing units in photonic applications, such as optical communication and computing networks.
