dc.description.abstractThe Na2SO4 − Dy samples were obtained by slow evaporation method. The spectroscopic methods were used to study the mechanisms of formation of electron and hole trapping centers. Intrinsic recombination emission of 2.9–3.1 eV and impurity emission of 2.55 eV and 2.15 eV are excited at 4.0–4.5 eV. Intrinsic SO3− 4 − SO− 4 and impurity Dy2+ − SO− 4 trapping centers were revealed. The local levels corresponding between the electron and hole trapping center are 4.0–4.5 eV.ru
