Abstract

We prepared silver iodobromide double-structured grains with different iodide content in the core and the shell, and determined their ionic conductivities by measuring their dielectric loss responses. The responses were reproduced quantitatively by the calcula- tions based on Pauly-Schwan/Hanai (PS/H) theory, which is therefore proved to be an effective means for designing the silver iodo- bromide double-structured grains suitable for latent image formation.
