摘要: The thermalization of electrons in copper nanoparticles embedded glass is investigated using femtosecond pump-probe spectroscopy. time dependent induced transmission enhanced near the surface plasmon resonance nanoparticles, as opposed to static one obtained with thermomodulation measurements. In addition, a slowing process electron cooling lattice temperature observed at resonance. These observations show importance quasiparticle collisions confined metallic structures.
