Abstract

Abstract: Different preperation methods (KBr-KI、AgI、organic RI) of iodide-rich phase were studied in this experiments. It was observed that iodide-rich methods affected photographic sensitivity of the emulsion prepared apparently. The difference of distribution of iodide ions in AgX microcrystals and dislocation on the surface of the microcrystals, as explored by XRD, may explain the change of sensitivity.

Key words: silver bromoiodide, multi-structure, iodide-rich phase, X-ray diffraction
