摘要
系统地研究了乳剂制备过程中总碘量、碘溴化钾溶液中碘浓度及向反应体系中引入碘液的时间对于T颗粒碘溴化银乳剂微晶的几何性质(形态比、颗粒大小分布及颗粒几何形状)的影响。同时报道了一种新型中间凹下碘溴化银T颗粒的制备。
The influence on the aspect ratios, shapes and size distribution of T-grain is studied of the total iodide content, iodide concentraton in a solution of potassium iodobromide, and the time to add iodide to the precipitation vessel when preparing T-grain silver iodobromide emulsion microcrystals. A novel AgBr(Ⅰ) T-grain with middle-cavea surface is prepared and reported.
