Study the Sensing Properties of Gold, Silver, and Aluminium Coupling Plasmon Nano-Sphere and Homo-Dimers

Abstract

FDTD simulations are used to investigate the homo- dimer nanostructures as localized surface plasmon resonance when the predicted LSPR wavelengths of Ag, Au, and Al nanospheres in a homo-dimer arrangement are equated, the findings show that the Ag and Al homo-dimer exhibits a higher LSPR shift than the Au homo-dimer. Enhancements in intensity are brought about in the junction as a result of the interaction between the homo-dimer nanoparticle and it. It has been determined that the field enhancement for homo-dimer nanostructures composed of gold, silver, and aluminum has been compared, and theoretically, values in the visible range of DU.v-U.v. have been projected to be between 108 and 109.
