Erbium(III) ion-doped borate-based glasses for 1.53 μm broad band applications

[EN] Novel erbium(III) ion-doped borate-based glasses (Er: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 = 2, 4 and 6) were determined by using absorption spectrum of 1 mol% ErO doped glass. These JO parameters were utilized to derive radiative properties for various excited states of erbium(III) ions. Emission cross-section for I → I transition of erbium(III) ions was computed through McCumber theory. The decay curves for (H, S) and I levels were recorded and analysed. All the results of Er: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
