Abstract
The results of an experimental study of the photoconductivity induced by a giant-pulse ruby laser in crystalline anthracene lead to the following conclusions: (1) Up to laser intensities of 5×1025 photons cm-2 sec-1, charge carriers are generated by a three-photon process. (2) The dominant mechanism for the production of charge carriers involves the photo-ionization of singlet-exciton states. (3) A cross section of 10-19 cm2 at λ=6940 was determined for the photo-ionization of singlet-exciton states. (4) A bimolecular rate constant of (5±3)×10-7 cm3 sec-1 for charge-carrier recombination in crystalline anthracene was directly determined.
