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 (Ωλ λ = 2, 4 and 6) were determined by using absorption spectrum of 1mol% 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 I13/2 → 4 I15/2 transition of erbium(III) ions was computed through McCumber theory. The decay curves for (2 H11/2 , 4 S3/2 ) and 4 I13/2 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.
