Abstract: This article examines the local atomic structure of neodymium ions introduced into boroaluminate (5 mol.% Nd2O3 ) and zinc phosphate (0.5 mol.% Nd2O3 ) glasses by extended x-ray absorption fine structure (EXAFS) spectroscopy near the Nd L3-edge. The reference spectra of neodymium oxide recorded at both the K- and L3-edges facilitated the identification of multielectron excitation features and enhanced the determination accuracy of local structural parameters. The findings revealed that, on average, neodymium ions in the boroaluminate glass are coordinated by approximately 9.6 oxygen atoms at a Nd–O distance of approximately 2.4 Å, whereas in the zinc phosphate glass, they are surrounded by approximately 6.8 oxygen atoms at approximately 2.3 Å.
