Enhanced Raman Scattering

In this paper, we summarize our results on the effect of changing size and shape of semiconductor and metallic nanocrystals. The change in size (from 3.5 to 1.1 nm) and shape (from spherical to rod) of CdSe nanocrystals is found to affect both their optical and nonradiative properties. In gold quasi-spherical nanocrystals, results on the dependence of the electron-phonon relaxation of the surrounding medium are presented. For gold nanorods, results and conclusions on the mechanism of their self-assembly are presented. Enhanced Raman scattering on their surfaces is studied and compared with that on spherical particle surfaces.
