Structural and spectroscopic investigations on Eu3+-doped alkali fluoroborate glasses

Structural and luminescence behaviour of Er3+ doped telluro-fluoroborate glasses

“…The band around 1010 cm -1 corresponds to the stretching vibration of BO 4 group and a band around 690 cm -1 is due to the oxygen bridge between two trigonal boron atoms forming the B-O-B bending vibration [24]. The band at around 450 cm -1 is attributed to the Te-O-Te or O-Te-O linkage bending vibrations [25][26][27].…”

Luminescence investigation on Eu–pillar[5]arene-based diglycolamide (DGA) complexes: Nature of the complex, Judd–Ofelt calculations and effect of ligand structure

“…The radiative transition probability A for a transition ψJ→ ψ′J′ can be calculated from the following equation: [17,36,37,[40][41][42] A(ψ ψ ψ ψJ, ψ′ ψ′ ψ′ ψ′J′ ′ ′ ′) = A ed + A md (7) where A ed and A md are the electric-and magnetic-dipole radiative transition probabilities, which are obtained from Eqs (4) and (5), respectively.…”

Luminescence characterization of Eu 3+ doped Zinc Alumino Bismuth Borate glasses for visible red emission applications

“…In the present work the value of J-O parameter Ω 6 has been neglected in evaluating the radiative properties as its influence is negligible [44][45][46]. The J-O parameters thus evaluated are given in Table 2.…”
