Abstract

Plasmonic structures, driven by collective electron oscillations in metallic nanostructures, are vital in nanophotonics for manipulating light at the nanoscale. This study focuses on metal nanogaps of 20 nm fabricated via Photolithography and atomic layer deposition, exhibiting tunable transmission resonances across visible to near-infrared wavelengths. Raman spectroscopy of Poly (p-phenylene vinylene) (PPV) on these metal nanogaps reveals altered Raman linewidths without significant changes in Raman frequencies, elucidating the intricate interplay between plasmonics and molecular interactions. These findings are pivotal for advancing our understanding of plasmonic effects at the molecular level, offering insights for innovative optoelectronic device design and sensing applications.
