Conducting carbon films are irradiated by high energy ion beam and persistent photoconductivity has been found from the irradiated samples. A complex distribution of traps created mostly by random displacement of carbon atoms by an energetic ion beam from the polymeric matrix showed a persistent photoconductivity at low temperatures down to 50 K. From the photo decay constants and the magnitude of photocurrent the density of traps and the corresponding activation energies have been calculated
