Optical properties of silver nanoparticles deposited on glass and silicon substrates

In this work, we presented a simple method for the growth of silver nanoparticles (Ag NPs) on glass and silicon substrates using the RF magnetron sputtering. The optical properties of Ag NPs deposited on glass and silicon substrates were studied. The surface plasmon resonance (SPR) peak of Ag NPs strongly depend on its size, shape and surrounding dielectric environment. The SPR peak of Ag NPs shows red shift with increase in the particle size as well as with the substrate effect.
