Description
Summary:•Theory of the radiative characteristics of the doped nanocrystals in nanocomposite.•Decay rates of optical centers in magnetodielectric nanocomposite.•The analytical expressions for the electric-dipole and magnetic-dipole decay rates. We present results of the theoretical study of optical characteristics for the small-radius optical centers in the subwavelength ellipsoidal nanocrystals embedded in a medium. Analytical expressions are obtained for the electric-dipole and magnetic-dipole decay rates of excitations of optical centers in a magnetodielectric nanocomposite.
