Resonant Raman Scattering by quadrupolar vibrations of Ni-Ag Core-shell Nanoparticles
H. Portales, L. Saviot, E. Duval +5
Low-frequency Raman scattering experiments have been performed on thin films consisting of nickel-silver composite nanoparticles embedded in alumina matrix. It is observed that the…

Raman scattering by electron-hole excitations in silver nanocrystals
H. Portales, E. Duval, L. Saviot +3
Raman scattering experiments from silver nanocrystals embedded in films of amorphous silica are reported. In addition to the low-frequency peak due to vibrational quadrupolar modes…
