Radiative Recombination of Frenkel Excitons in Solid c60 Under Radiation Damages

The behavior of the emission of the excitons localized at different X-centers at the radiation damages by electron beams with an energy of 1.8 MeV and argon ions in the plasma of glow discharge is studied. The nature of X-centers, which contribute to the emission of excitons near energies of 1.5 and 1.6 eV, is discussed. It is shown that the essential reconstruction of the energy spectrum of excitation is observed with increase in the radiation dose, as a result of the radiation damages of C60 molecules.
