Abstract: NiS nanoparticle is found to be an effectively chemical sensitizer of silver halid emulsions.The sensitivity and contrast of NiS-sensitized AgBr emulsion is higher than that of sodium thiosulfate-sensitized AgBr emulsion without enhancing much fog.

Key words: nickel sulfide, nanoparticle, chemical sensitization, silver halide
