Effect of Spheroidal Magnetized Nanoparticles on the Luminescence of Quantum Dots

A spectral model is constructed for the luminescence of a two-component exciton-activated quantum dot (QD)–spheroidal plasmon nanoparticle (NP) system in a homogeneous external magnetic field in the approximation of a dipole electric polarizability tensor of the nanoparticle with dissipation of the exciton energy in the NP taken into account. A tensor representation of the dielectric permeability of the magnetized electron plasma of the metal is used, which is responsible for the formation of the characteristics of the electric field in the spheroid. It is found that with a change in the eccentricity of the spheroid, the luminescence spectrum of the system changes, reflecting the effect of the external magnetic field on both the radiative and the dissipative properties of the binary QD–NP complex.
