文摘

Surface plasmon resonance (SPR) based fiber optic sensor with bi layers of Pt-ZnO is theoretically studied. Sensitivity and figure of merit of sensor enhance with increase in thickness of Pt layer for all thicknesses of ZnO layers. Also, for a fixed thickness of Pt layer, sensitivity and figure of merit rise as the thickness of ZnO layer is raised from 0 nm to 20 nm 40 nm Pt–20 nm ZnO based SPR sensor demonstrates the highest sensitivity of 3161 nm/RIU.
