Abstract

From in situ Raman measurements during potassium doping of pure C60 films to a structure KxC60 in the range of 0 x 6 we found a continuous change of line intensities for the Ag modes of the stable phases in this material. No shift of these modes with doping was observed, which proves a strict phase separation. The Raman line at 1467 cm-1 for pristine C60 is due to oxygen contamination and is assigned to positively charged fullerene states. The intrinsic pinch mode of the pristine material is at 1458 cm-1 and has a linewidth of 4 cm-1.
