摘要

We have developed an ultrafast, light-scattering spectroscopic system combining a conventional microscope with a pump-probe setup. We successfully measured the surface plasmon resonance band for the individual gold particles with a mean radius of 40 nm. The results on the pump-probe experiment demonstrate that both the electron-phonon and the phonon-phonon coupling processes in the individual gold particles take place with the lifetimes of 4 ps and > 25 ps, respectively.
