摘要/Abstract

摘要： 使用反馈式微机控制双注乳化仪,在晶体生长过程特定时间内,加入一定量的草酸盐,制得了草酸根离子处于晶体次表面的立方体溴化银微晶乳剂,并对其进行传统的硫加金化学增感、Zn(Ⅱ)-EDTA或Cd(Ⅱ)-EDTA增感以及光谱增感.对实验过程的考察和感光性能的测试结果表明,Zn(Ⅱ)-EDTA或Cd(Ⅱ)-EDTA对细微粒溴化银颗粒乳剂均有显著的增感效应;Zn(Ⅱ)-EDTA或Cd(Ⅱ)-EDTA增感可在传统硫加金增感基础上与光谱增感协同作用,三者具有兼容和可加和性;Zn(Ⅱ)-EDTA或Cd(Ⅱ)-EDTA增感可在传统硫加金增感与光谱增感协同作用的基础上,与草酸根内部掺杂增感兼容,实现四者的协同作用,而不引起乳剂灰雾增加.

Abstract: In the emulsifying process of AgBr microcrystals in the double-jet apparatus controlled by a microcomputer,a certain amount of oxalate salt was injected at specific time and pAg into a reactor to prepare AgBr grain emulsions in which oxalate ions were doped at subsurface of AgBr microcrystals,and which were sensitized respectively by sulfur plus gold,sulfur plus gold plus Zn (Ⅱ)-EDTA or Cd(Ⅱ)-EDTA,and dye. The results from the whole experiments and sensitometric results from these emulsions showed: 1) that sensitization of Zn (Ⅱ)-EDTA or Cd (Ⅱ)-EDTA on silver bromide emulsion was affirmed;2) That a cooperation sensitization of Zn (Ⅱ)-EDTA or Cd (Ⅱ)-EDTA,sulfur plus gold,and dye could be carried out to make a higher level of sensitization;3) That a cooperation sensitization of Zn (Ⅱ)-EDTA or Cd (Ⅱ)-EDTA,on the basis of (sulfur plus gold) and dye,with oxalate-doped was carried out to make a higher level of sensitization without any increase in the level of fog.
