The Kretschmann setup had multiple layers, a BK7 prism, silver, barium titanate (BaTiO3), titanium dioxide (TiO2), and graphene. The BaTiO3 and TiO2 coatings were sandwiched between two silver layers. The sensitivity of 260°/RIU has been achieved. The graphene layers are added to the configuration to improve sensitivity and as a bio-compatibility agent. This configuration can be used for biochemical sensors.
