A surface-enhanced Raman scattering (SERS) composite substrate based on the synergy between Au@ZIF-8 nanoparticles (NPs) and multilayer Au/Al 2 O 3 thin films (MLFs) was designed to achieve electromagnetic field enhancement by coupling localized surface plasmon resonance (LSPR) with bulk plasmon pol...
