Abstract

Silver nanoparticles have been generated in aqueous buffer solution using a water-soluble silicon phthalocyanine sensitizer. Red light illumination (660 nm LED) was performed under aerobic conditions at ambient temperature in the presence of TEOA as a reductant. Structural characterization of the Ag nanoparticles formed was carried out by transmission electron microscopy (TEM). The resulting silver particles, depending on irradiation time and choice of procedure, were found to have a spheric shape and a narrow size distribution of 5-10 nm.
