Site of Doped Eu in BaMgAl10O17 Studied by X-Ray Absorption Fine Structure

The sites that doped divalent Eu ions occupy in BaMgAl 10 O 17 were studied by X-ray absorption fine structure (XAFS) measurement. The radial structural function and the Fourier-filtered EX-AFS wiggle derived from the observed XAFS spectrum suggested that Eu ions occupy the Beevers-Ross and/or anti-Beevers-Ross sites. Observed XANES spectrum also could be explained by Beevers-Ross site occupation.
