Two-dimensional transition metal dichalcogenides (TMDs), particularly tungsten diselenide (WSe2), exhibit exceptional optoelectronic properties, including strong light-matter interactions and tunable exciton behavior, making them promising for nanophotonic applications. This work investigates a hybrid system comprising a WSe2 monolayer integrated with a plasmonic metasurface of Au-nanobumps to enhance photoluminescence (PL) through exciton-plasmon coupling and strain-induced bandgap modulation. The WSe2 monolayers were mechanically exfoliated and transferred onto a laser-patterned Au-nanobump array fabricated via femtosecond laser printing, offering a scalable alternative to conventional lithography. Optical characterization showed a threefold enhancement of photoluminescence intensity of WSe2 monolayer lying on a nanobump compared to WSe2 on a flat gold substrate, what attributed to localized plasmon-exciton interactions and strain effects. The study demonstrates a cost-effective, lithography-free approach for tailoring hybrid TMD-plasmonic systems, enabling precise control over optical properties for next-generation optoelectronic devices.
