A photoemission study of potassium intercalated trimetal‐nitride fullerene Dy 3 N@C 80 is reported. A continuous electron doping to the carbon cage with increasing potassium intercalation levels is observed as shape changes in the carbon‐sensitive ultra‐violet photoemission spectrum. X‐ray photoemission shows that the valence electronic state of the trivalent Dy ions is not affected by the additional charge in the fullerene cage. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
