The authors present ultrafast transient reflectivity measurements performed on metallic tin nanoparticles with an average radius between 20 and 60 {angstrom} in amorphous matrix. The samples, grown using an evaporation-condensation technique, were characterized by a relatively low nanocrystals size dispersion and a negligible clusters-matrix interaction. The excitation decays exhibited a size-dependent behavior, which is interpreted in terms of the important role played by the electron-surface interactions.
