摘要：
The results of the tracer diffusion of Ag+ by chemical microsectioning technique in AgBr/I sheet crystals up to the solubility limit in the temperature range 110-240°C are presented. The monotonic increase in the diffusivity and decrease of the activation enthalpy for diffusion with the increase of the iodide component in AgBr result from the decrease of the formation energy for Frenkel defects with the increase of elastic strain introduced by the oversized iodide ions. © 1991, Taylor & Francis Group, LLC.
