Abstract

Novel erbium(III) ion-doped borate-based glasses (Er³⁺ :BCNF) by conventional melt-quenching technique were designed and synthesized. The glasses were characterized for their structural, vibrational and spectroscopic properties. The nephelauxetic ratio, bonding parameters, and Judd-Ofelt (JO) intensity parameters (Ω_λ λ = 2, 4 and 6) were determined by using absorption spectrum of 1 mol% Er₂ O₃ doped glass. These JO parameters were utilized to derive radiative properties for various excited states of erbium(III) ions. Emission cross-section for ⁴ I_13/2 → ⁴ I_15/2 transition of erbium(III) ions was computed through McCumber theory. The decay curves for (² H_11/2 , ⁴ S_3/2 ) and ⁴ I_13/2 levels were recorded and analysed. All the results of Er³⁺ :BCNF glasses revealed that the studied glasses are efficient and thermally stable and could be suitable for display devices, optical amplification and green laser applications.
