Localized and propagating surface plasmon co-enhanced Raman spectroscopy based on evanescent field excitation

The localized and propagating surface plasmon co-enhanced Raman scattering of 4-mercaptopyridine was observed based on evanescent field excitation. The most effective coupling of the localized and propagating surface plasmons resulted in a >50 times enhanced signal relative to signals obtained on...

Zusammenfassung:The localized and propagating surface plasmon co-enhanced Raman scattering of 4-mercaptopyridine was observed based on evanescent field excitation. The most effective coupling of the localized and propagating surface plasmons resulted in a >50 times enhanced signal relative to signals obtained on vacuum-deposited silver film.
