Abstract
Due to the electron-lattice interaction, photoexcitation in C60 induces bond distortion, which forms a self-trapping exciton and reduces the symmetry of C60 from Ih to D5d. The dynamical process of forming the self-trapping exciton is simulated by demonstrating the evolution of both bond distortion and electronic states. It is found that the relaxation time for the exciton trapping time is about 90 fs, which is four times faster than of charge transfer in C60.
