Abstract

Investigation of the photoinduced processes in pure C₆₀ films was performed by means of sub-100 fs resolution spectrometer. Excitation by 100 fs laser pulses with photon energy above and below the mobility edge revealed that both charged and neutral components appear during the excitation pulse. At both excitation wavelengths electrons and holes are generated by direct optical excitation and not due to singlet-singlet annihilation. Anions are created with a delay of 10^-13 - 10^-11s in a result of electrons capture by C₆₀ molecules.
