This study aims to determine the effect of neodymium concentration on barium sodium borate glasses. The glass samples were fabricated using the melt-quenching technique for analyzing the physical properties, absorption spectra, and NIR emission spectra. The twelve absorption bands increased with the increase in Nd3+ concentration. The most intense absorption band is centered at 583 nm (corresponding to the 4I9/2→4G5/2 transition), which is chosen to investigate the NIR emission spectra. The NIR emission spectra exhibited the most intense emission band at 1,077 nm under 583 nm excitation wavelength, corresponding to the 4F3/2→4I11/2 transition, respectively. The maximum NIR emission intensity was observed at the glass sample with 2 mol% of Nd3+. The NIR emission spectra and the results from Judd-Ofelt theory confirm that 2 mol% of Nd3+-doped Ba-Na-B glasses with a 1,077 nm emission in this work might be used as a NIR laser medium material. © (2023), (Suranaree University of Technology).
