Plasma-polymerized fluorocarbon Ag–Cu nanocomposites: Nanostructure optimization for superior SERS sensitivity by Joonhyuk Lee, Sung Hyun Kim, Seok-Kyun Son, Sang-Jin Lee

“…This paper proposes a method to finely control the distribution of Ag and Cu nanoparticles within a plasma–polymer–fluorocarbon (PPFC) thin film by adjusting the sputtering power density to improve SERS performance. We fabricated Ag–Cu nanocomposite PPFC (CAP) thin films by sputtering at different mid-range-frequency sputtering densities, resulting in variations in the optical absorption wavelengths and changes in the Ag/Cu ratio, as confirmed by an X-ray photoelectron spectroscopy analysis. …”
