摘要: 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感光材料,在保证微粒的前提下,寻找一些有效的增感剂能达到微粒高感的目的.冠醚化合物是一类新型的增感剂。近年来,冠醚化合物增感卤化银乳剂已有过一些报道[1,2]。作者[3,4]对硫杂冠醚化合物增感澳化银乳剂做过一些探讨。

Abstract: A series of crown ether compound I~Ⅷ was 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 was I<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 in crown ring is greater than or equal to five,the crown ether show sensitization effect on silver halide emulsion.
