[The charge transferring between silver nanoparticles and R6G].

In this paper, we studied the charge transferring between silver nanoparticles and R6G molecules by UV-Vis absorption spectra, SERS and fluorescence spectra. The results indicate that the charge transferring process can be completed by forming complex between silver nanoparticles and R6G molecules. As a result, the absorption band of complex can be seen in the absorption spectra, the Raman modes of R6G are largely enhanced and the fluorescence of R6G is effectively quenched.

[The preparation of Ag/AgCl nanoparticle and its resonance scattering spectroscopic study].

Putting the AgCl nanoparticle as crystal nucleus and in the condition of the existence of tri-sodium citrate, the Ag+, which covers the surface of AgCl nanoparticle, photochemically reduces to Ag and thus Ag/AgCl composite nanoparticle is obtained. The spectroscopic characters of Ag/AgCl nanoparticle in aqueous solution have been studied. There are two resonance scattering peaks at 310 and 590 nm, and an absorption peak at 400 nm.
