Abstract:
Formulas for the rates of spontaneous radiative decay of excitation of luminescent centers located in subwavelength spherical core–shell nanoparticles and in the nanocomposite matrix are derived. Effective medium models and local field problems concerning the optical properties of activated nanocomposites based on core–shell nanoparticles are discussed. A detailed analysis of two modern approaches to the problem of spontaneous transitions in luminescent centers located in homogeneous spherical nanoparticles is made.
