Judd-Ofelt intensity parameters of Nd³⁺ ions doped in BaO-ZnO-B₂O₃ glasses Available to Purchase

Nd₂O₃ doped glass samples with compositions xNd₂O₃-(100-x) [0.1BaO-0.4ZnO-0.5B₂O₃]; x = 0.5, 1.0, 1.5 and 2.0 have been prepared using melt quench technique. Optical absorption spectra have been recorded for prepared glass samples at room temperature. The spectral intensities of Nd³⁺ transition observed in absorption spectra have been calculated by using Judd-Ofelt theory. The intensity parameters (Ω₂, Ω₄ and Ω₆) have been estimated by applying least square fit method on the experimental (f_exp) and calculated (f_cal) oscillator strengths. The values of Ω₂ increase with the increase in concentration of Nd³⁺ ions in the host glass matrix which suggests that the Nd³⁺ ions are covalent nature with the surrounding ligand.
