Abstract

The theoretical investigation of the electron, hole and phonon spectra in the spherical nanoheterosystem CdS/β-HgS/H2O is performed within the effective mass approximation in the dielectric continuum model. The Hamiltonian of the exciton–phonon system is established in the representation of second quantization. The energy of the exciton basic state (Eex) renormalized due to the interaction with phonons is obtained. The existence of a crook in the Eex curve depending on the β-HgS shell thickness is proved and explained. A satisfactory correlation between the theoretical and experimental results is obtained.
