Plasmon resonance sensitivity in fine metal particle
  The sensitivity of the wavelength position of surface plasmon resonances in prolate and oblate fine metal particles to the refractive index of an embedding solution, a particle shape, and electron temperature is studied theoretically in the framework of different analytical methods. All calculations are illustrated on the single potassium nanoparticle as an example.
