The Influence of the Solution pAg on the Interstitial Concentration of Silver Halides. A Semi-Quantitative Treatment

ABSTRACT

The concentration of silver interstitials in silver halide microcrystals generally increases with the pAg in the solution before coating. This is not in agreement with the expectations and with conductivity results on large single crystals. The large surface to volume ratio of emulsion grains is suggested to be responsible for this conductivity behaviour. The surface can accommodate enough charge to compensate the excess space charges in the solution and the solid.
