Abstract

The solgel process has been successfully used to prepare silver/silica nanocomposites After drying in air at 50°C for 30 min samples were heat treated in air at 100 200 400 and 500°C for the formation of silver nanoparticles Evolution of silver nanoparticles in the amorphous SiO2 matrix as a function of annealing temperature has been studied Characterizations were made by Xray diffraction ultravioletvisible and infrared spectroscopy Mechanisms of silver clusters formation in the densified silica matrix with respect to thermal treatment are discussed
