|Publisher:||PHYSICS IIT ROORKEE|
|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.|
