Paper Abstract

Investigation of photo-induced processes in Sn nanocrystals covered by a submonolayer of C60 anions was performed with femtosecond pump-probe method. Samples in thin films were excited by 150 fs laser pulse at 400 nm (109 W/cm2). Dynamics of difference transmission and reflection has been measured in the spectral range of 1 100-1700 nm. The dynamics of relaxation are quite different for various nanostructures depending on the deposition mode and the ratio of tin and fullerene content. Relaxation, observed in the samples, is explained by electron transfer from excited anions to metal followed by energy transfer from excited C60 molecules to anions in the ground state.
