The QSBoBa glasses with chemical formula 10 Quartz sand + (50-x) B2O3 + 10BaO + 30Na2O + xNd2O3 (x = 0, 0.5, 1, 1.5, and 2 mol%) were prepared by a conventional melt-quenching technique. The successfully fabricated glass samples will be analyzed based on their physical, structural, optical and luminescent properties. The XRD and FTIR spectra have been included to observe the complete structural properties. Optical absorption spectra revealed several characteristic transitions, with a prominent hypersensitive transition4I9/2→4G5/2 at 584 nm, indicating an increasing asymmetry and disorder at higher Nd3+ concentrations. The photoluminescence emission spectra demonstrated strong radiative transitions of4F3/2→4I11/2, particularly the 1060 nm, which is critical for solid-state laser applications. The emission intensity decreased when the concentration of Nd3+ was increased. Decay lifetime analysis confirmed this trend, with longer lifetimes at 0.5 mol% and 1.0 mol% and shorter lifetimes at higher concentrations, suggesting quenching effects at elevated doping levels. Radiative parameters, including transition probability (AR) and emission cross-section (σe), identified 0.5 mol% as the optimal doping concentration, achieving high radiative efficiency without significant quenching. The broad emission bandwidth at 1330 nm further indicates the material’s potential for broadband optical amplifiers in telecommunications. The Nd3+-doped QSBoBa glass system exhibits promising properties for solid-state lasers, optical amplifiers and sensors, with 0.5 mol% offering the best balance between emission efficiency and structural stability. This study confirms the versatility and potential of the QSBoBa glass system for advanced photonic applications. Copyright (c) 2025 Journal of Metals, Materials and Minerals.
