Optical properties of anisotropic core-shell pyramidal particles.

Christina M Sweeney¹, Warefta Hasan, Colleen L Nehl, Teri W Odom.

Abstract

This paper describes an approach to fabricate anisotropic core-shell particles by assembling dielectric beads within fabricated noble metal pyramidal structures. Particles with gold (Au) shells and different dielectric cores were generated, and their optical properties were characterized by single particle spectroscopy. Because of their unique geometry, these particles exhibit multiple plasmon resonances from visible to near-IR wavelengths.
