The influence of a change in the nanostructure, obtained at the different temperatures and times of annealing on the Raman vibrational spectra of the Cu-C-60 films of different compositions was studied. The appearance of additional lines, their displacement, and also sharp increase in the background was observed in the spectrum of the Raman scattering. This modification of the vibrational structure of fullerenes is connected with the distortions of the molecules, caused by the additional interaction to the van der Waals one. (C) 2004 Elsevier B.V.
