Zinc Alumino Bismuth Borate (ZnAlBiB) glasses doped with different concentrations of neodymium are prepared by using the melt quenching technique to study their physical, absorption and luminescence properties to understand the lasing potentialities of these glasses. From the absorption spectra various spectroscopic parameters and Judd–Ofelt (JO) parameters are evaluated. These JO parameters are used to calculate the transition probability (A), radiative lifetime (τ_R), and branching ratios (β_R) for most of the fluorescent levels of Nd³⁺. The emission spectra recorded for these glasses gives three prominent transitions ⁴F_3/2→⁴I_9/2, ⁴F_3/2→⁴I_11/2 and ⁴F_3/2→⁴I_13/2 for which effective band widths (Δλ_P) and stimulated emission cross-sections (σ_se) are evaluated. Branching ratios and stimulated emission cross-sections measured for all these glasses show that the ⁴F_3/2→⁴I_11/2 transition under investigation has the potential for laser applications. The intensity of Nd³⁺ emission spectra increases with increasing concentrations of Nd³⁺ up to 1mol% and beyond 1mol% the concentration quenching is observed. The high stimulated emission cross-section and branching ratios from the present glasses suggests their potential for infrared lasers. From the absorption and emission spectral studies it was found that, 1mol% of Nd³⁺ ion concentration is optimum for Zinc Alumino Bismuth Borate glasses to generate a strong laser emission at 1060nm.
