摘　　要：多结构溴碘化银核壳乳剂的众多优点主要缘于颗粒结构中碘的巧妙应用．首先，正空穴被颗粒内富碘的ＡｇＢｒＩ相所捕获，而电子则被外壳所吸收，使电子与正空穴分离，减少了正空穴与导带电子的复合，从而可以提高乳剂的色盲感光度［１］．其次，多层结构颗粒表面所含的碘提...ifferent preperation methods (KBrKIAgIorganic RI) of iodiderich phase were studied in this experiments. It was observed that iodiderich 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.\=
