Abstract

Borate glasses of different Nd2O3 concentrations were prepared by a quenched method. The vitreous samples were all obtained in an amorphous form. The effect of the addition of small amounts from Nd2O3 on the short, intermediate, and long-range ordered structure of xNd2O3 - (40-x) B2O3 -30 BaO - 25 Na2O - 5 P2O5 (0 ≤ x ≤ 7 mol%) has been investigated using different experimental tools. Thermal heat treatment transforms the glass to glass ceramics as evidenced by XRD patterns and TEM-EDP micrographs. It has been investigated how Nd2O3 affects NMR characteristics by altering the coordination of both boron and neodymium. Through the application of 11B NMR spectroscopy, the quantitative proportion of boron atoms with four-coordinated neighbors (N4) has been readily evaluated. The influence of Nd2O3 on the NMR parameters has been examined by considering the changing coordination environments of both boron and neodymium atoms. As the Nd2O3 content increases, the ability of neodymium oxide to act as a network modifier enhances, which is substantiated by the declining fraction of boron tetrahedral units (N4) and the chemical shift of boron nuclei (δ). These observations corroborate the anticipated role of Nd2O3 in modifying the network structure.
