Modified Drude model for small gold nanoparticles surface plasmon resonance based on the role of classical confinement
TLDR
By decreasing the diameter of NP, the restoration force becomes larger and classical confinement effect becomes more dominant in the interaction and it is shown that the imaginary part of permittivity is more sensitive to the diameter variations. Expand
