摘　　要：本文研究了ＡｇＢｒＣｌ转化乳剂的离子电导和光电导。随着乳剂中溴含量的增高，其离子电导也随之升高，而光电子寿命则降低。ＡｇＢｒＣｌ乳剂的离子电导主要取决于其组成；ＡｇＢｒＣｌ转化乳剂的光电子寿命主要受隙间银子浓度的影响，隙间银离子浓度越大，光电子寿命越短。Ionic conduction and photoconduction of AgClBr conversion emulsion is studied.Withthe increase of bromide content of the AgClBr conversion emulsions,elevated ionic conductivities and decreased photoelectron life times are observed.It is thought that thefonic conductivity of AgClBr emulsion depends mainly on their compositions instead oftheir manufacture process.The photoelectron life time of AgClBr conversion emulsionis strongly influenced by the concentration of intersticial silver ion of the emulsion.Thehigher of the concentration of intersticial silver ion,the shorter of the photoelectron lifetime.
