Despite tremendous progress achieved in the field of plasmonic nanoantennas, recently significant efforts have been contributed for studying the light-matter interaction of plasmonic nanoantennas with few-layer transition metal dichalcogenides (TMDs). Monolayer and Bilayer molybdenum disulfide (MoS2) has intense attention in recent years for their unique optical properties. However, mono and bilayer MoS2 suffers from insufficient light-matter interaction because of its atomically thin nature. Plasmonic nanostructures can be easily integrated and boost the light-matter interaction of 2D TMDCs. In this study, we demonstrated the enhanced Photoluminescence and photocatalytic properties of bilayer MoS2 toward Hydrogen Evolution Reaction (HER) using plasmonic structures. Near field enhancement of quadrupole gap surface plasmonic structures have been optimized by Taguchi design methods.
