Abstract

Barium aluminates doped with Eu2+ and Dy3+ (BaAl2O4:Eu2+,Dy3+) were prepared with the combustion synthesis at temperatures between 400 and 600 °C as well as with the solid state reaction at 1500 °C. The concentrations of Eu2+/Dy3+ (in mole% of the Ba amount) ranged from 0.1/0.1 to 1.0/3.0. The electronic and defect energy level structures were studied with thermoluminescence (TL) and different synchrotron radiation spectroscopies: UV-VUV excitation and emission, XANES and EXAFS. Theoretical calculations using the Density Functional Theory (DFT) were carried out in order to compare with the experimental data.
