Cooperative sensitization on silver bromoiodide (AgBr/I) grains emulsion by oxalate and sulfur-plus-gold

After sulfur-plus-gold sensitization on silver bromoiodide (AgBr/I) microcrystal emulsions prepared by the emulsifying process in the double-jet apparatus controlled by a microcomputer, a certain amount of oxalate salt (1×10-1、1×10-2、1×10-3and 1×10-4mol/molAg) was respectively added at a specific ti...
