中文摘要	a sandwich structure consisting of ag nanoparticles (nps), p-aminothiophenol (p-atp) self-assembled monolayers (sams), and ag nps was fabricated on glass and characterized by surface enhanced raman scattering (sers). the sers spectrum of a p-atp sam in such sandwich structure shows that the electromagnetic enhancement is greater than that on ag nps assembled on glass. the obtained enhancement factors (ef) on solely one sandwich structure were as large as 6.0 +/- 0.62x10(4) and 1.2 +/- 0.62x10(7) for the 7a and 3b(b(2)) vibration modes, respectively. the large enhancement effect of p-atp sams is likely a result of plasmon coupling between the two layers of ag np (localized surface plasmon) resonance, creating a large localized electromagnetic field at their interface, where p-atp resides. moreover, the fact that large ef values (similar to 1.9 +/- 0.7x10(4) and 9.4 +/- 0.7x10(6) for the 7a- and b(2)-type vibration modes, respectively) were also obtained on a single sandwich structure of au nps/p-atp sams/ag nps in the visible demonstrates that the electromagnetic coupling does not exist only between ag nps but also between au and ag nps.
