▎ 摘　　要

NOVELTY - A surface plasmon resonance sensor comprises optical fiber sensor main portion comprising photonic crystal fiber, analyte sensing area and graphene-coated gold/silver nanopillars, where the photonic crystal fiber has cladding diameter (D) of 125 um and side length (L) of 1 mm, gold/silver nanopillars have radius (r) of 25 nm, two-dimensional structure of the optical fiber sensor comprises two cores, air holes, gold nanopillars, graphene and silver nanopillars provided front side of the photonic crystal fiber and the surface plasmon resonance sensor is based on D-shaped photonic crystal fiber. USE - Surface plasmon resonance sensor. ADVANTAGE - The surface plasmon resonance sensor has high sensitivity, simple structure, small volume, wide detection range and strong resistance to corrosion, and effectively prevents oxidation of silver nanopillars.
