Outline of Final Research Achievements |
The aim of this study is the sensitivity improvement a vibrational spectroscopy by surface plasmon resonance which is induced at the surface of metal nanoparticles or planes. The optical field enhancement is amplified at nano-gap between metal nanoparticle and metal plane, which is utilized as substrates for surface enhanced Raman scattering. Vibrational sum frequency generation spectroscopy was observed with the nano-gap, showing five-fold signal enhancement.
