摘　　要：用络合—沉淀法制备了卤化银含量３０ｇ／Ｌ，粒子大小２０ｎｍ以下的ＡｇＢｒ／Ｉ纳米粒子乳剂，研究发现：ＡｇＢｒ／Ｉ纳米粒子表现出较大的表面活性，并由此导致了其乳剂具有比常规乳剂低得多的感光度和高得多的灰雾，乳剂的最佳碘含量增加到了１１％，硫增感对纳米粒子乳剂没有效果，但硫加金增感表现出有效性。The AgBr/I nanometer grains emulsion is prepared by complexing precipitation,of which the AgX content is 30 g/L and the grains average diameter is below 20 nm .Results show that the nanometer grain emulsion has much lower photographic sensitivity and much more fog oweing to the high surface activity of the nanometer grains.The optimum iodine content at which the emulsion has the highest photographic sensitivity increases to 11%.Sulfur sensitization has no effect on AgBr/I nanometer grain emulsion,but sulfur plus Aurum sensitization seems to be effective.
