The nanocomposite particles of SiO2 @ Ag core shell were successfully prepared. Silica core has been synthesized by means of modified Stober process which was coated by silver to fabricate silica@ silver core- shell in 5 nm size. Silver nanoparticles were prepared by the reduction of Ag ions and PVP as a caping agent. Such core-shell nanoparticles opened new vision to be used in a wide range of applications such as: antibacterial, optics, electronics, catalystics, solar cells according to desired shape and size.
