Abstract

In this study, the effect of size and dielectric environment surrounding of Au and Ag nanoparticles on the wavelength and intensity of SURFACE PLASMON RESONANCE (SPR) peak were investigated by using the MIE THEORY and FDTD software. The absorption peak was observed at about 500, 400 nm in calculated spectra of Au and Ag respectively. A red-shift was observed for SPR peak with increasing of nanoparticles size. Also SPR peak is shifted to longer wavelength with increasing of refractive index surrounding. A linear dependence between refractive index surrounding of nanoparticles and SPR wavelength shift was observed. The maximum slop was observed for particle size of 20 nm. Sensitivity of SPR peak by altering of refractive index for Ag nanoparticles is more than Au nanoparticles. The calculated results are in agreement with experimental results.
