Synthesis and Physicochemical Properties of Nickel-Containing Nanoparticles

Abstract

Ni and Ni/Pd nanoparticles stable in the liquid phase and in the adsorbed state were prepared by radiation-chemical reduction of metal ions in aqueous-organic inverse micellar solutions. The optical absorption and luminescence spectra of nanoparticle solutions were studied immediately after preparation in the presence of oxygen and without it. Changes in these spectra, resulting from evolution of the nanoparticles in the course of storage and from pH variation, were examined.
