Abstract
The coordination environments of Er and Lu in sodium silicate glasses are probed through a unique analysis of L-3 X-ray absorption near edge structure (XANES) combined with extended X-ray absorption fine struct ure (EXAFS). By using the observed splitting of the empty 5d manifold of the lanthanides in combination with the EXAFS data, we demonstrate that Er and Lu are 6-coordinate in well-defined sites with relatively high symmetry.
