EARLY STAGES OF LATENT IMAGE FORMATION IN AGCL GRAINS UNDOPED OR DOPED WITH IRIDIUM IONS

The behavior of photoelectrons captured by traps and early stage latent image formation in undoped or Ir-doped AgCl grains was studied by photoconductivity-modulation techniques. Silver atoms were formed at the grain surface of undoped grains in ∼10−4 s and near Ir ions of Ir-doped grains several seconds after exposure of the samples to a light pulse.
