Abstract

The formation of Ag2 – xS /Ag binary nanoparticles in an aqueous colloid dispersion of Ag2S under irradiation leads to an asymmetry in the optical absorption spectrum as a consequence of the Fano resonance due to the interaction between the excitons of semiconductor nanoparticles and the plasmons of metallic nanoparticles. Aqueous dispersions from different stability regions containing Ag2S nanoparticles have been studied. Sunlight, UV and laser irradiation leads to the partial reduction of silver in the dispersion and the formation of the Ag2 – xS /Ag particles depending on the initial state of the dispersion and the conditions of irradiation.
