Summary: The study investigates the optical properties of gold nanoparticles (Au NPs) using COMSOL Multiphysics simulations, exploring the effects of geometry, environment, and temperature. Various shapes, including nanospheres, nanorods, and core/shell structures, were analyzed in different media, and the dielectric function was modeled as a function of size and temperature. Results showed that larger particle sizes and higher temperatures cause a red-shift in localized surface plasmon resonance (LSPR), offering insights for tailoring Au NP properties for applications like imaging and drug delivery.
