Title of Paper:

Calculation of curvature dependent surface plasmon resonance in gold nanospheroid and nanoshell

Journal:

JOURNAL OF NANOPARTICLE RESEARCH

Summary:

In this paper, theoretical calculations
based on dipole-limit are performed to investigate
the effects of curvature on the surface plasmon
resonance (SPR) properties of nanometer size gold
spheroid and shell. By comparing the aspect ratio
with the shell thickness, we demonstrated that the
curvature radius is a common better factor that can be
used to predict the SPR wavelength and shift fashion.
For nanospheroid, increasing the ratio of curvature
radius corresponding to the climaxes leads to an
increase in the ratio of SPR wavelength, whereas
increasing the ratio of curvature radius of outer and
inner surface in nanoshell leads to an decrease in the
ratio of SPR wavelength. As a morphologic factor,
curvature radius plays an important role in affecting
the distribution of electron density, and consequently
controlling the SPR frequency.
