Abstract

Stable gold nanoparticles with surface plasmonresonance tunable from visible (Vis) to near-infrared (NIR)are deposited via a direct sputtering methodology on largearea polyethylene terephthalate (PET) to be used as effective,flexible NIR surface-enhanced Raman scattering (SERS) substrates.AnO2 plasma treatment of PET is used to tailor growthdynamics, geometry, and plasmonic properties of nanoparticles.The O2 plasma treatment of PET results also in effectiveimprovement of nanoparticle anchoring on the plastic substrate,providing more stable, flexible SERS systems. Thefunctionality of fabricated SERS substrates has been testedusing benzylthiol, and SERS enhancement factors in the range104 have been achieved, which are comparable with thosereported in literature for gold nanostructures fabricated onsilicon substrate. These results attest the great potentiality ofthis methodology for the production of cost-effective flexibleand reusable large-scale SERS substrates.
