Abstract

The synthesis of Ag@SnO₂ nanocomposite particles with core-shell morphology has been reported. Ag colloidal particles were synthesized by a well-documented aqueous reduction technique using NaBH₄ as reductant, trisodium citrate as a stabilizer and AgClO₄ as the source for the Ag⁴⁺ ion. The formation of metal oxide shell on the Ag nanoparticles was monitored by the UV-Visible spectroscopy and was confirmed by the TEM images of the resultant core-shell particles. The presence of a SnO₂ shell on the silver nanoparticles was also corroborated by XPS results. Optical property of the nanocomposite was investigated by photoluminescence spectroscopy.
