摘　　要：研究了K4[Fe(CN)6]掺杂剂对溴碘化银颗粒乳剂感光性能的影响,结果表明掺杂剂的掺杂量、掺杂位置以及在乳剂颗粒内部的分布区域对乳剂的感光性能都有影响。掺杂位置接近表面或接近内核时效果明显,掺杂位置接近富碘区域时,乳剂的感光度上升的不明显,较佳的掺杂量为1×10-6mol/molAgNO3。The effects of dopant K4 [Fe（CN）6 ] on the photographic properties of the iodobromide T-grain emulsion were studied. It was found that the doping amount, location and distribution of the dopant had significant effects on photographic properties of the emulsion. The nearer to the surface or the kernel of the grain, the more remarkable the effects were. The sensitivity could be decreased if the doping region was near the iodide. The best doping amount was 1 × 10^- 6 mol/molAgNO3.
