Local environment dependent linewidth of plasmon absorption in gold nanoshell: Effects of local field polarization

摘要：

The linewidth of the plasmon absorption of a gold nanoshell was theoretically studied by using a
Drude model and quasistatic approximation. Increasing the dielectric constant of the core or
surrounding can broaden the absorption peak linearly. A mechanism based on the polarization
direction of the local electric field in the gold shell was investigated to illuminate the effect of
dielectric constant on the broadening of the plasmon absorption. The perpendicular local field
enhances the scattering of the oscillatory electrons and brings a loss of electron phase coherence,
which in turn results in a broadening of the plasmon absorption linewidth
