The study of resonance Raman scattering spectrum on the surface of Cu nanoparticles with ultraviolet excitation and density functional theory.

Abstract

Cu colloid was prepared by oxidation-reduction; it was relatively steady in fixed conditions, with size about 10-30 nm. The Raman spectrum of p-hydroxybenzoic acid (PHBA) in Cu colloid solution with the ultraviolet (UV) excitation at 325 nm, was obtained, even it is usually difficult to obtain Raman signals in Ag or Au in the UV region. It was found that… (More)
