Abstract

The local structure around the Nd³⁺ ions in 60%-exchanged sodium β″-alumina was studied by X-ray absorption spectroscopy. The analysis of the Nd L₃-edge experimental data shows that neodymium ions are mainly located near mid-oxygen (9d) sites. The local environment of Nd is slightly changed compared to crystallographic positions: the Nd-O(5) distance is shortened by 0.36 Å, while the Nd-Al(6c) is increased by 0.13 Å. The values of Debye-Waller factors of different coordination shells are discussed in terms of vibrational correlation.
