摘要:
The present invention provides a photographic emulsion comprising silver halide grains, a dopant, and a grain surface modifier. The dopant is a transition metal complex comprising a nitrosyl or thionitrosyl ligand with a transition metal selected from the group consisting of ruthenium and osmium. The grain surface modifier is a transition metal selected from Group VIII of the periodic table.
