Thermoluminescence and synchrotron radiation studies on the persistent luminescence of BaAlsub(2)Osub(4):Eusup(2+), Dysup(3+). In: INTERNATIONAL CONFERENCE ON ADVANCED MATERIALS, 11th, September 20-25, 2009, Rio de Janeiro, RJ. <b>Abstract...</b> Disponível em: http://repositorio.ipen.br/handle/123456789/22868.http://repositorio.ipen.br/handle/123456789/22868Barium 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.openAccessbarium compoundsaluminatesdoped materialseuropiumdysprosiumthermoluminescencesynchrotron radiationResumo de eventos científicoshttps://orcid.org/0000-0001-7028-0878
