MgF2 prism/rhodium/graphene: efficient refractive index sensing structure in optical domain.A theoretical study of a noble surface plasmon resonance (SPR) based sensing probe has been carried out.  The sensing probe consists of a magnesium fluoride (MgF2) prism with its base coated with rarely used noble metal rhodium (Rh) and a bio-compatible layer of graphene.

MgF2 prism/rhodium/graphene: efficient refractive index sensing structure in optical domain.A theoretical study of a noble surface plasmon resonance (SPR) based sensing probe has been carried out.  The sensing probe consists of a magnesium fluoride (MgF2) prism with its base coated with rarely used noble metal rhodium (Rh) and a bio-compatible layer of graphene.  The thickness of Rh and the number of graphene layers have been optimized for maximum sensitivity in a constraint set by the detection accuracy (DA).  For the operating wavelength of 632 nm, the optimized sensing probe Rh (12 nm)/graphene (single layer) demonstrates sensitivity of ~259 degree/RIU with corresponding DA of ~0.32 degree-1 while for 532 nm of excitation, the optimized sensing probe Rh (12 nm)/graphene (three layer) exhibits sensitivity of ~240 degree/RIU and DA of ~0.27 degree-1.
