This study focused on substrate hydrophilicity/hydrophobicity, which has been insufficiently considered in surface-enhanced Raman scattering (SERS) spectroscopy, and investigated the relationship between molecular adsorption amount and SERS characteristics. Using graphene oxide (GO) and reduced graphene oxide (rGO) thin films, and employing rhodamine 6G as a model molecule, we systematically evaluated adsorption amount, wettability, and Raman enhancement characteristics. This fundamental research aims to elucidate the governing factors of the SERS effect.
