Iron in photographic gelation-I.The influence of Fe~(2+) ions in gelation medium on chemical sensitization of silver halide

摘要

In this paper the influence of Fe~(2+) ions in Gelatin Medium on the sensitivities of silver halide emulsions with sulfur or sulfur plus gold sensitizers is studied. The drop of emulsion sensitivity is shown because of doed Fe~(2+) ions in gelatin medium. In addition its influence mechanism is also explored.
