Sažetak
Powder sample of pure BaAl2O4 and one doped with 4.9 at% Eu in relation to barium were prepared by a hydrothermal method and subsequent annealing at 1100 oC for 4h. Both samples were characterized by synchrotron based X-ray absorption spectroscopy. The transmission mode Eu and Ba L3- edge X-ray absorption experiments of the prepared samples were performed at DELTA beamline 10. The normalized Eu L3-edge XANES spectrum of Eu-doped sample was investigated in comparison to the spectra of Eu2O3 and AlEuO3 standards, and to the one of a glass sample containing both Eu2+ and Eu3+. The white line feature of the Eu-doped BaAl2O4 sample at 6983.4 eV clearly revealed the presence of trivalent europium in the doped sample. The Ba L3-edge XANES spectra of pure BaAl2O4 and Eu-doped BaAl2O4 samples showed that in the doped sample the host material remained in its original Ba2+-state. The presence of impurity phases such as Eu2O3, AlEuO3 and BaO in the prepared Eu-doped sample can be excluded on a basis of the obtained XANES spectra.
