Localized surface plasmon resonance and damping mechanisms in transition metals

This work reports calculated dependences of localized surface plasmon resonance (LSPR) parameters and damping mechanisms on nanoparticle size for transition metals. Using Mie theory, peak energies, amplitudes and FWHM were analyzed. Results show dependence on electronic structure and damping. Smaller nanoparticles exhibit higher absorption and lower scattering, while larger ones show red-shift and narrowing of resonance peaks.
