Abstract

The resonance scattering and emission spectra of AgX (X=Cl, Br and I) nanoparticles in liquid phase show that AgCl and AgBr nanoparticles all exhibit four resonance scattering peaks at 330, 400, 470 and 680 nm, and three fluorescence peaks at 340, 400 and 470 nm.While AgI nanoparticles produce five resonance scattering peaks at 340, 400, 437, 470 and 680 nm, a strongest fluorescence peak at 434 nm and three other peaks at 340, 400 and 470 nm.The influence of the concentration of the system of AgX nanoparticles on the resonance scattering signals is consistent with that on the fluorescence intensities.And the resonance scattering intensity of AgCl, AgBr and AgI systems is 110, 130 and 80 times of the fluorescence intensity, respectively.That is, the relationship between fluorescence and resonance scattering is exist.The fluorescence mechanism of AgX nanoparticles has been proposed, and the reason that there is the correlation between the fluorescence and resonance scattering has been explained.

Key words: AgX nanoparticle in liquid phase, interface fluorescence, resonance scattering
