| description |
A method is proposed for determining the temperature of hot electrons in a metallic nanoparticle embedded
in a dielectric matrix under ultrashort laser pulses irradiation. The amplitude and power of the longitudinal
spherical acoustic oscillations as functions of density and elastic properties of the medium, the laser pulse
duration, the electron temperature, radii of particles, and the electron-phonon coupling constant are obtained.
The efficiency of the electron energy transfer from heated noble nanoparticles to a surrounding environment is
estimated for different electron temperatures. |
