本文研究了(100)及(111)晶体在改变氯与溴化银比例时对其吸附菁染料光谱性能的影响。增感染料之吸收光谱取决于吸附菁染料之卤化银的结晶性态,在立方形晶体乳剂中,氯化银含量高时,具有J-峰(最大值),在吸附菁染料的晶格中,具有20—40%溴化银时,这一聚集倾向就将消失。吸附于高溴含量八面体乳剂颗粒的染料J-聚集体,随着颗粒中氯/溴比的增加而向H-聚集体迁移。

In this paper, the influence of (100) and (111) crystals on the spectral properties of (100) and (111) The absorption spectrum of the sensitizing dye depends on the crystalline state of the silver halide adsorbing the cyanine dye. In the cubic crystal emulsion, the silver chloride has a high J-peak (maximum) in the crystal lattice of the adsorbed cyanine dye , With 20-40% silver bromide, this tendency to aggregate disappears. Dye J-aggregates adsorbed to high bromine content octahedral emulsion particles migrated towards H-aggregates as the chlorine / bromine ratio in the particles increased.
