• The DC-photoconduction of both pure and heavily tetracene doped anthracene single crystals has been investigated in both the strongly and weakly absorbing wavelength regions. With sandwich-type cell and under monochromatized illumination, the electron photocurrent (i-) and hole photocurrent(i+) were measured separately. With coped crystals, the current produced by the thermal excitation from the tetracene excited state could be measured for various temperature region. The thermal activation energy for carrier generation from the tetracene excitation state was measured to be 0.35eV for i+ and 0.24eV for i-. As the excited state of tetracene included is 2.4eV from the ground state, energy gap of crystalline was deduced to be 3.0eV.
