DFT and synchrotron radiation study of Eu2+ doped BaAl2O4.

Original language description

The structural distortions resulting from the size mismatch between the Eu2+ luminescent centre and the host Ba2+ cation as well as the electronic structure of BaAl2O4:Eu2+(,Dy3+)were studied using density functional theory (DFT) calculations and synchrotron radiation (SR)luminescence spectroscopy.The modified interionic distances as well as differences in the total energies indicate that Eu2+ prefers the smaller of the two possible Ba sites in the BaAl2O4 host.The calculated Eu2+ 4f7 and 4f65d1 groundlevel energies confirm that the excited electrons can reach easily the conduction band for subsequent trapping.
