BPN449: Plasmon Engineering the Nanocrescent

We present a systematic numerical study of plasmon resonance in 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. Because its wide tunability, high local field enhancement, and geometry which utilizes both a sharp edge and intra-particle coupling, the nanocrescent is a structure well-suited for in vivo biological applications.
