title: [The interface fluorescence and resonance scattering spectral properties of Ag2S nanoparticles in liquid phase].
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 x 10(-5) mol x 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.
