Abstract

The nonequilibrium carrier dynamics in Ag nanoparticles was explored by femtosecond optical pump-probe spectroscopy. Metal-dielectric nanocomposite materials containing Ag nanoparticles of different sizes were prepared by thermal treatment of aluminophosphate glasses. The ultrafast relaxation dynamics of the electron scattering on the 10^-13-10^-12 sec scale shows size- and pump power-dependent properties. The two-photon absorption process in nanoparticles of different sizes is discussed. The laser-induced coherent vibrations of nanoparticles were observed in transient transmission experiments.
