چکیده

We determined the surface-enhanced Raman scattering of the plasmonic hybrid nanotubes of fullerene C60-polythiophene-Ag or Au nanoparticles (NPs) which were synthesized via the template-based electrocopolymerization of terthiophene-linked fullerene C60 and terthiophene-modified Ag NPs or Au NPs using a nanoporous alumina membrane as the template. The combination of plasmonic activity and chemical stability may allow for a variety of new applications.

Guided-mode-resonance-coupled plasmonic-active SiO(2) nanotubes for surface enhanced Raman spectroscopy.

We demonstrate a surface enhanced Raman scattering (SERS) substrate by integrating plasmonic-active SiO(2) nanotubes into Si(3)N(4) gratings. First, the dielectric grating that is working under guided mode resonance (GMR) provides enhanced electric field for localized surface plasmon polaritons on the surface of metallic nanoparticles. Second, we use SiO(2) nanotubes with densely assembled silv...
