摘要：

Investigation of photoinduced processes in different C-60-Sn nanostructures excited by 150 fs laser pulses at 400 nm (10(9) W/cm(2)) was performed with femtosecond supercontinuum probing of difference absorption and reflection in the spectral range of 400-1600 nm. The dynamics of relaxation are quite different for various nanostructures depending on the deposition mode and the ratio of tin and fullerene content. Non-monotonic relaxation, observed in the samples with Sn nanocrystallites, is explained by electron exchange between C-60 and the metal. (C) 2003 Elsevier Science B.V. All rights reserved.
