| dc.description.abstract | Emission lines of free excitons and excitons bound to axial centers have been observed in the luminescence spectra of CdP2-D48 crystals doped with Mn, Sn, and Sb at 10 K. Bands models of excitons bound to axial centers (Mn, Sn, Sb) are proposed. The luminescence of crystals doped with Fe does not correspond to the axial centers band scheme. It is shown that direct transitions in excitonic band are polarized and in the case of indirect transitions they ate unpolarized. The direct band gap is due to allowed transitions Г1 → Г1 and Г2 → Г1 in E||c and E⊥c polarizations, respectively. The coefficient of the energy shift in the temperature range of 2–10 K in E‖c and Е⊥c polarizations differs (ΔE/ΔT = 3.5 meV/K, E‖c and 1 meV/K, Е⊥c). | en_US |
