The problem of plasmon resonance in spherical metal nanoparticles incorporated into an anisotropic dielectric medium is studied theoretically. Analytic solution is obtained in long-wavelength approximation for the case of weak uniaxial anisotropy. It is shown that medium anisotropy causes shifts of plasmon frequency from its position in an isotropic medium, which are different for plasmons with dipole...
The surface plasmon energy in spherical silver nanoparticles embedded in silica host matrix depends on the size and temperature of the nanoparticles. The dependences of the surface plasmon energy were studied for silver nanoparticles in the size range 11–30 nm and in the temperature interval 293–650 K. As the size of the nanoparticles decreases or the temperature increases, the surface plasmon resonance...
