摘　　要：系列冠醚化合物对卤化银乳剂的增感作用初探符玉华，金磊，赵艳，马凤云，周本茂（中国科学院感光化学研究所，北京１００１０１）关键词冠醚，卤化银乳剂，增感作用微粒高感是卤化银感光材料的发展方向。一般说来卤化银颗粒越小，其感光度越低，为了制备微粒高感的卤化银...A series of crown ether compound I￣Ⅷwas used to sensitize cubic AgBr and AgIBr emulsion,respectively.The results show that(1)the esensitivity of the emulsions were increased obviously by using crown I￣Ⅳand the order of the ability to increase sensitivity wasI<Ⅱ<Ⅲ<Ⅳ;(2)the sensitivity of AgBr emulsion was ecreased by using crown ether V;(3)the sensitivity of emulsion was not changed by using crown Ⅵ￣Ⅷ. According to the results,a rule of the sensitization effect of crown ether on silver halide emulsion may be suggested:only when the number of O(or S,Se, Te,N)in crown ring is greater than or equal to five,the crown ether show sensitization effect on silver halide emulsion.
