摘要: The effect of the mutual positions plasmonic gold fi lms and a layer analyte (malachite green mitoxantrone molecules) on surface-enhanced Raman scattering (SERS) was investigated. When excitation emission in plasmon resonance region (531 nm 632.8 nm) used SERS intensity sandwich configuration up to five times higher compared with "analyte under film" arrangement 60 than for lm" case.
