The local field enhancement associated with the plasmonic resonance in metallic nanostructures has attracted intense research interest for its role in a number of useful optical phenomena such as surface-enhanced Raman scattering. In reality, the surface plasmon resonance, or the collective oscillation of the nanostructure's electrons, inevitably relax some of its energy through phonon and generates heat. Some nanostructures turned out to be especially efficient in such photothermal energy conversion and found applications in thermotherapy of cancer and optically triggered drug delivery. In this Project, we explore the photothermal effects of our gold Nano-Crescent structures.
