The 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 re-combination 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 SO34- - SO4- and impurity Dy2+ - SO4- trapping centers were revealed. The local levels corresponding between the electron and hole trapping center are 4.0-4.5 eV.
