Saadoon Centre of Nanotechnology and Advanced Material, University of Technology, Iraq Journal Article 2025 01 19 In the case when predicted LSPR wavelength values of Ag, Al, and Au nano-spheres in homodimer arrangement are equated, FDTD simulations are utilized for studying homo-dimer nano-structures as localized surface plasmon resonance (SPR). Results indicate that silver and aluminum homo-dimer shows higher shift of LSPR when compared to gold homo-dimer. It is interacting with a homo-dimer nanoparticle (NP), which raises the junction’s intensity.
