In this paper we present the effect of gold, silver and oxide thicknesses on the sensitivity of Surface Plasmon Resonance (SPR). SPR sensor with enhanced sensitivities can be realized based on gold/silver films. Surface Plasmons (SP) are electromagnetic waves that transmit along the interference between a metal and a dielectric film, and the electromagnetic wave of the surface plasmons is coupled to oscillations of free electrons in the metal. SPR has attracted interest in many applications such as solar cells, chemical and biological sensing. The potential sensor application by using gold/silver nanocrystal enhanced SPR phenomenon. Sensitivity is a significant parameter to assess the sensor's performance. Essentially, sensitivity is determined by the force of light and matter interaction.
