摘要/Abstract

摘要： 本文研究了K₄[Fe(CN)₆]掺杂对溴碘化银T-颗粒乳剂感光性能的影响.结果表明,掺杂剂的掺杂量以及掺杂位置对乳剂的感光性能都有影响.K₄[Fe(CN)₆]的掺杂量在每克乳剂31×10^-9-31×10^-11mol之间时,乳剂感光度都有提高.最佳掺杂量为每克乳剂31×10-10mol.掺杂位置接近表面时效果相对较好,表明K₄[Fe(CN)₆]是浅电子陷阱掺杂剂.当掺杂剂的掺杂量大于每克乳剂31×10^-8mol,且掺杂位置在乳剂颗粒较深内部时,乳剂的感光度反而下降.

关键词: 掺杂, 浅电子陷阱, 过渡金属络合物, T-颗粒乳剂

Abstract: The effect of K₄[Fe(CN)₆] doping on the photographic properties of the iodobromide T-grain emulsion was studied in this paper.It was found that both the doping amount and the position had significant effects on the photographic properties of the emulsion.When the doping amount was between 3.1×10^-9 to 3.1×10^-11 mol per gram of the emulsion,the photographic sensitivity increased by the doping.The sensitivity increased more when the doping position was near the grain surface and the optimum amount of dopant was 10^-10 mol per gram found in the study.When the doping amount was more than 10^-8 mol per gram of the emulsion and the doping position was in deep interior of the grain,the sensitivity decreased.

Key words: dope, shallow electron traps, transition metal complex, T-grain emulsion
