In this work the expression for optical conductivity of spherical metal nanoshell as a function of internal and external radii of nanoshell and photon energy – Fermi energy ratio is obtained. Quantization of electron energy in nanoshells is shown to lead to the appearance of an oscillating dependence of optical conductivity on the light frequency. An explicit expression of oscillating addends for optical conductivity is obtained.
