Abstract The electrochemical properties of an evaporated C60 film were studied by voltammetry in organic electrolyte solution. Four reversible reduction waves were observed, corresponding to the formation of alkali metal salts of fullerene, A x C60 (A∶ Li, K, Rb,x=1, 2, 3, 4). The voltammograms observed for each cation species were compared and discussed in relation to the cation radius. The change of optical density spectrum by the redox reactions was measured in the wavelength range of visible light. The resistivity of a C60 film protected by a polyimide film decreased rapidly by four orders of magnitude after the electrochemical doping of potassium ions.
