Endohedral lanthanide metallofullerene ions were generated by laser ablation of graphene and the corresponding metal salts MCl3 (M = Ce, Pr, Nd, Gd, Tb, Dy and Ho) and studied with a FTICR mass spectrometer. Typically, multi-metallofullerene ions of TbnC2m+2≤n≤780≤2m≤176 and Ho6C2m+2≤n≤674≤2m≤162 were observed. The results show that the formation of multi-EMF ions containing lanthanides that have +3 and + 4 oxidation states is easier than those containing +2 oxidation states in the process of laser ablation.
