چکیده

We report on the application of Raman scattering as a probe to study 4-mercaptopyridine (4-Mpy) surface-modified CuO nanocrystals. Enhanced Raman scattering from 4-Mpy adsorbed on CuO nanocrystals was observed. The Raman signals displayed 10(2) enhancement compared with those of 4-Mpy in solution. We compared the Raman spectra of 4-Mpy molecules adsorbed on CuO nanocrystals and Ag, Cu substrate. A particular feature of the semiconductor substrate that was different from the metal substrate was revealed. The excitation wavelength-dependent behavior was clearly observed.

Local protonation control using plasmonic activation.

Localized protonation of 4-mercaptopyridine (4-MPY), activated by light in the presence of silver nanoparticles is monitored under ambient conditions using surface-enhanced Raman scattering (SERS) and tip-enhanced Raman scattering (TERS). The reaction can be controlled by the excitation wavelength and the atmospheric conditions, thus, providing a tool for site-specific control of protonation.

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 vacuum-deposited silver film.
