The method of ion-implantation synthesis of endo- and exofullerenes is developed. The samples of fullerenes containing iron, platinum or their mixture are prepared. Spectrophotometric investigations of low-concentration solutions of metallofullerenes dissolved in organic solvents (toluene) are carried out. As shown, the bonding of metal atoms to the fullerene leads to the broadening of the absorption-spectrum line width and to the absorption-maximum shift to the long-wave part of the spectrum. The half-width and the shift are increasing in the series of С60–С60 ? Pt–С60 ? Fe–С60 ? Fe ? Pt.
