Plasmon localized

Keywords, optical fiber sensor surface plasmon, localized surface plasmon, biomolecules... [Pg.425]

From close inspection of the image, it is found that the highest enhancement occurs at the isolated dimer (A), and the enhancement observed at the rim or at the defect sites in the assembly is lower. This observation implies that the enhancement is the highest in the dimer and becomes lower with increasing size of the assembly. The finding may have some correlation with the relatively low SERS enhancement reported in close-packed assemblies. Plasmon localization at the rim of the assembly may have some similarities with photon localizations at the boundaries of photonic... [Pg.155]

In 1994, we proposed that a metallic needle having a nano-tip at its apex be employed as a nano-light-source for microscopy attaining nanometric spatial resolution [2]. Later, we expanded the technique to Raman spectroscopy for molecular nano-identification, nano-analysis and nano-imaging. In this chapter, we give a brief introduction to local plasmons and microscopy using a metallic nano-needle to produce the local plasmons. Then, we describe the microscope that we built and... [Pg.19]

Near-Field Optical Imaging of Localized Plasmon Resonances in Metal Nanoparticles... [Pg.39]

In this chapter, we have provided an overview of near-field imaging and spectroscopy of noble metal nanoparticles and assemblies. We have shown that plasmon-mode wavefunctions and enhanced optical fields of nanoparticle systems can be visualized. The basic knowledge about localized electric fields induced by the plasmons may lead to new innovative research areas beyond the conventional scope of materials. [Pg.51]
