Abstract
The sensitivity of the surface plasmon resonance wavelength position in prolate and oblate metal nanoparticles to the refractive index of an embedding solution, nanoparticle shape, and temperature is studied theoretically. The influence of dissipation factor on plasmon resonance is discussed as well. The new approach specifying the optimal nanoparticle shape to reach the maximal sensitivity is proposed. The calculations are illustrated on the example of Na nanoparticle.
