Abstract S2- and Ag+ form stable Ag2S nanoparticles in the presence of sodium dodecyl sulphate(SDS).It exhibits a strong resonance scattering peak at 470 nm and a strong fluorescence peak at 470 nm when excitation wavelength is at 200 nm.The effects of TAA and Ag+ concentration on the fluorescence intensities are consistent with those on the resonance scattering signals.The resonance scattering and fluorescence intensities all increase with Ag+ concentration in the range of 0-8.0×10-5 mol·L-1.The results verified that there is a correlation between the fluorescence and resonance scattering.The fluorescence is the interface fluorescence of Ag2S nanoparticles in liquid phase.
