Ag2S Nano-Particles Prepared in Reverse Micelles Used for Sulfur Sensitization

doi:10.7517/j.issn.1674-0475.2008.05.385

Abstract

Abstract: In this paper 3—5 nm Ag₂S particles were prepared in the reverse micellar system and used as novel sensitizer in AgCl cubic and {100} tabular microcrystal emulsions.The novel sensitizer shows an effective sensitizing ability for AgX emulsion,and it is superior to the traditional Na₂S₂O₃ sensitizer because by using it comparatively high sensitivity can be obtained with lower fog density.To illustrate the evolution mechanism of the sensitizer clusters and explain their excellent sensitizing properties,diffuse reflectance spectroscopy(DRS) was used as a probe on the AgX microcrystal surface.

Key words: silver halide emulsion, sulfur sensitization, silver sulfide, nano-sized, reverse micelles
