| Summary: | The Judd-Ofelt analysis of neodymium nanoparticles (NPs) doped zinctellurite glass denoted as Nd (NPs) - ZnTe glass were performed to determine their spectral parameters. A glass sample of Nd (NPs) - ZnTe glass with chemical composition of 0.47TeO2 + 0.2B2O3 + 0.29ZnO+0.05Nd2O3 was synthesized by using conventional melt quenching method. We select 0.05 mol fraction of Nd-NPs in tellurite glass as it gives the optimum results for glass stability and spectral intensities. The Judd-Ofelt parameters were determined by using least-square fitting method. It was found that the observed that Nd (NPs) - ZnTe glass exhibit judd-ofelt parameters as follows; ω2 = 2.623, ω4 = 0.174, ω6 = 0.837 and found in the following ω2 ˂ ω4 ˂ω6 trend. The hypersensitive transition was highly related to the ω2 parameter. Furthermore, the hypersensitive at 4I9/2→4G5/2 transition affect the value of ω2 which satisfies the selection rule Δs=0, Δl≤2 andΔJ≤2. The ω4 parameter was related mainly to the bulk properties of the host matrix meanwhile the ω6 parameter was related to the rigidity of the glass matrix. Therefore, the investigated glass materials may provide a good material for optical fiber. © 2024 Author(s).
