In this simulation work, comparative study of surface plasmon resonance (SPR) based sensor designed with gold (Au), Aluminium (Al), Silver (Ag) are numerically investigated to improve the performance parameter of device using Ni-Antimonene layer in the visible range of light at wavelength of 633nm. In this device configuration, different metals (Ag/Au/Al), a diamagnetic material (Fe2O3), Nickel (Ni) and 2D material Antimonene (Sb) is used with CaF2 glass prism using Kretschmann configuration with angle interrogation method. The angle interrogation method is used to examine the performance of the device. The performance parameters of SPR sensor such as sensitivity, detection accuracy (DA), quality factor (QF) has been calculated. The thickness of metals (Au/Al/Ag) and number of different material thickness has been optimized by using genetic algorithms to improve the performance of device. The present study reveals that Ag metal based SPR Sensor exhibit a higher sensitivity as compared to Al and Au based SPR sensor at 55 nm of thickness. At 55nm thickness of Ag minimum reflectance curve has been obtained in comparison with Au and Al. The studied multilayer configuration of SPR sensor device using different metal Au/Al/Ag with Fe2O3, Ni and Antimonene in presence of glass prism, the maximum sensitivity 3100/RIU is obtained in case of Ag. The sensitivities of Au and Al metals are 660RIU-1, 2040RIU-1 respectively which is less in comparison to Ag metal. The different performance parameter of SPR sensor such as sensitivity, full width at half maximum (FWHM) value, DA, figure of merit (FoM), limit of detection (LoD) is calculated for all three metals but in the case of Ag performance is good compared to Au and Al. The penetration depth (PD) 110.5nm and 3D plot of transverse electric (TM) field intensity have also been plotted. The proposed SPR sensor using Ag metal with highest sensitivity value has capability to detect the different liquid analytes in the field of biosensing application with large uses in biomedical field in visible range.
