Abstract:
This report represents the effective method to enhance surface Plasmon resonance (SPR)
on Ag films. Ag films of different thickness are deposited by pulsed laser deposition
technique. To enhance surface sensitivity surface plasmons has been used through
various spectroscopic measurements such as diffraction, interference and Raman
scattering etc. the surface Plasmon resonance (SPR) technique has been employed to
characterize optically Ag/glass film of different thickness. The morphology of the film
exhibiting SPR responses under different processing condition were analyze by the AFM
imaging through ND-MDT machine. The experimental SPR reflectance shows that it is
shifted continuously with the increasing number of pulses & decreased with higher
number of pulses. Theoretically SPR dip angle were calculated by winspall-302
software. This SPR based system shows a application as a sensors such as biological and
chemical sensing application.
