Abstract

We present a systematic numerical study of plasmon resonance of the nanocrescent. We show that by varying the nanocrescent geometry, the plasmon resonance peak can be tuned into the near-infrared and local field enhancement can be increased significantly, with maximum enhancement of the electric field amplitude of approximately 100 for realistic geometric parameters. Because of its wide tunability, high local field enhancement, and geometry which utilizes both sharp features and intra-particle coupling, the nanocrescent is a structure well suited for in vivo cellular imaging as well as in vitro diagnostic applications.
