CVD-grown graphene-on-Au characterization and sensing using Kretschmann-based SPR
A Kretschmann-based surface plasmon resonance (SPR) sensing method was used to determine the refractive index and thickness of graphene thin films. The measured complex refractive index (n,k) values of graphene on Au at 670 nm and 785 nm wavelength are 2.85, 0.74 and 3.1, 1.19 respectively. In further analysis, the analysis of sensing performance of graphene on Au SPR sensor for ethanol detection was obtained using Finite Difference Time Domain (FDTD) method. With the addition of graphene layers, the sensitivity, detection accuracy and quality factor of the SPR sensor increased at 670 nm.

Abstract

A Kretschmann-based surface plasmon resonance (SPR) sensing method was used to determine the refractive index and thickness of graphene thin films. The measured complex refractive index (n,k) values of graphene on Au at 670 nm and 785 nm wavelength are 2.85, 0.74 and 3.1, 1.19 respectively. In further analysis, the analysis of sensing performance of graphene on Au SPR sensor for ethanol detection was obtained using Finite Difference Time Domain (FDTD) method. With the addition of graphene layers, the sensitivity, detection accuracy and quality factor of the SPR sensor increased at 670 nm.
