Imaging of Surface Plasmon Resonance for Nano Material of Different Shapes

Abstract

Abstract The studies of Surface Plasmon Resonance SPR have focused on novel materials (gold and silver ). In this paper, four kinds of samples have been prepared also the system of plasmonic imaging with objective lens to excite the SPR our samples. The hot spot images for our different samples proved that the blue wavelength (405nm) can be excite the SPRs better than the green wavelength (532nm) for silver samples and the green wavelength can be excite the SPRs better than the blue wavelength for gold samples, also the increasing in consternation of AgNWs due to increasing in width of Gaussian hot spot.
