|Abstract: ||Nanostructuring of fullerene C60 beam deposited films is achieved by electrochemical reduction in a potassium hydroxide aqueous solution. Alkali fulleride clusters are formed at the electrode, as it
is illustrated by cyclic voltammetry, x-ray diffraction, and scanning tunneling microscopy.
Fluorescence emission from fluorophore doped fullerene reduced films was investigated by
fluorescence spectroscopy and scanning near-field optical microscopy. These techniques lead to results which also fit such nanometer-sized fulleride cluster interpretation. In particular, the fluorophore fluorescence lifetime decreases as long as aggregation in the film is more effective,which occurs with the increase of film thickness.|
