AFM and SEM show granule-like structure of the Co-C60 film. The mixture film deposited at RT includes the hilus on the surface suggesting accumulation of internal stress during phase separation. Raman spektra show 25 cm-1 downshift of Ag(2) C60 peak suggesting -Co-C60- polymerization in C60-based matrix of the NC film. Analysis of Raman spectra has revealed existence of amorphous karbon (a-C) in the NC matrix that argues C60 decomposition. The Ts increase to 200°C causes the surfaře hills smoothening. In parallel, downshift of the Ag(2) peak decreases to 16 cm-1 that implies more pronounced phase separation and lower -Co-C60- polymerization efficiency. Also, amount of a-C content slightly increases. Further Ts increasing to 400°C changes the NC structure dramatically.
