Abstract
A spectral model of luminescence of the two-component exciton-activated semiconductor quantum dot (QD) layered plasmon composite nanoparticle (CNP) with a dielectric core and a conductive shell in an external magnetic field is constructed, taking into account the inhomogeneity of the quasi-stationary electric field generated by QD in the CNP region, outside the framework of the approximation of the dipole polarizability of the CNP. The tensor formalism of describing the characteristics of the field in each of the layers of the CNP, as well as outside the CNP, is used. It is established that with a change in the structure of the nanocomposite, the parameters of its core or shell layer, the spectral response of the system to external magnetic field action changes. It is shown that the special form of the response is associated with the characteristic magnetic properties of the nanoparticle components acquired (under the action of the field).
期刊介绍:
Optics and Spectroscopy (Optika i spektroskopiya), founded in 1956, presents original and review papers in various fields of modern optics and spectroscopy in the entire wavelength range from radio waves to X-rays. Topics covered include problems of theoretical and experimental spectroscopy of atoms, molecules, and condensed state, lasers and the interaction of laser radiation with matter, physical and geometrical optics, holography, and physical principles of optical instrument making.
