摘要: 使用反馈式微机控制双注乳化仪,制备了甲酸根离子掺杂于颗粒次表面的立方八面体溴化银微晶乳剂.经计算此类颗粒上的(100)面与(111)面之比约为2:3.感光性能测试结果表明,甲酸根掺杂乳剂,无论是原始乳剂,还是经过化学增感,或染料光谱增感后的乳剂,其感光度都要明显高于相应的参考未掺杂乳剂(Sd/So≈2),而灰雾水平则无明显增长.

Abstract: By use of the double-jet apparatus controlled by a microcomputer, cubo-octahedral AgBr grain emulsions in which formate ions were doped at subsurface of AgBr microcrystals, were prepared. By calculation, the ratio of facet (100) to facet (111) of this kind of grains is about 2:3. The sensitometric results from these emulsions show that the sensitivities (Sd) of formate-doped emulsions, relative to those (S0) of the corresponding undoped ones as the controlled, regardless of whether it is primitive, or sensitized chemically and spectrally, were remarkably increased without a significant increase in fog density. (Sd/So≈2).

Key words: formate-doped, cubo-octahedral, silver bromide, sensitization
