Abstract

The formation of Ag clusters on silica colloidal nanoparticles was achieved by photoreduction of silver ions with visible laser irradiation. A mechanism of this process was proposed by observing the plasmon resonance bands of the silver clusters in UV–visible absorption spectroscopy. These Ag/SiO2 colloids are SERS-active and can be used to detect products that could be formed by heterogeneous catalytic reactions of ligands adsorbed on the colloidal surface.
