摘　　要：本文利用双注仪制备出中空立方体碘氯溴颗粒乳剂并研究其感光性能 .结果表明 :由于中空颗粒具有独特的孔洞结构 ,使位错、缺陷增加 ,填隙银离子浓度增加和电子陷阱增多 ,潜影形成效率提高 ,从而达到提高乳剂感光性能的目的 .The hollow cubic silver iodochlorobromide microcrystals were prepared.The relation between structure and property of the hollow cubic Ag(Br,Cl,I)microcrystal emulsions was studied by means of SEM and sensitometry.Compared with solid cubic Ag(Br,Cl,I) emulsions,the hollow cubic Ag(Br,Cl,I)grain emulsion has higher surface activity and higher sensitivity.The advantages of hollow cubic silver halide microcystals can be ascribed to their unique hole structure.
