Paper Abstract

In the present study, we report the growth of silver nanoparticles in SiO2 matrix by co- sputtering technique. The effect of deposition conditions on the formation of Ag nanoparticles were systematically studied using scanning electron microscopy (SEM), UV-Vis absorption studies. The optical absorptive nonlinearity of the nanoparticles was studied by using open aperture Z- scan techniques. The surface plasmon peak in the absorption spectra indicates the presence of Ag nanoparticles in the matrix. The open aperture Z-scan studies shows the Ag- SiO2 nanocomposites can be used as a good optical limiter.
