Abstract: Nanosized ZnS is found to be an effective chemical sensitizer of silver halide emulsions.The sensitivity and contrast of ZnS- sensitized AgBr emulsion are higher than that of the sodium thiosulfate-sensitized AgBr emulsion without enhancing the fog.

Key words: nanoparticle, zinc sulfide, silver halide, sensitizer
