Abstract : A model is proposed to describe the photoelectron decay process at room temperature in cubic AgCl microcrystals homogeneously doped with K4 Fe(CN)6 . By combining calculation of the kinetic equations resulted from the model with a microwave absorption dielectric-spectrum measuring technique, the capture cross-section and the trap depth of shallow electron traps induced by [Fe(CN)6 ]4- at room temperature are obtained, which are 3.560 x 10-17 cm2 and 0.115 eV, respectively. Based on the two parameters, the optimal doping amount of K4 Fe(CN)6 is easily gained to be 2 ppm by computer calculation.
