Electron-hole trapping centers in alkali metal sulfates with Dy3+ impurities

Electron-hole trapping centers in alkali metal sulfates with Dy3+ impurities

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 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. Int...
