Spectral parameters and visible fluorescence of Sm3+ in alkali–barium–bismuth–tellurite glass with high refractive index

Spectroscopic studies of Sm3+ and Eu3+ co-doped lithium borate glass

“…The assignment of these bands has been made on the basis of data from Refs. [16][17][18] and is listed in Table 1. These bands reveal characteristic Eu 3+ 4f-4f transitions, which are assigned as the transitions from the ground state 7 F 0 and the first excited state 7 F 1 to the higher energy levels.…”

Optical properties of Sm3+-doped CaF2 bismuth borate glasses

“…The measured and calculated oscillator strengths, and Judd-Ofelt intensity parameters of Sm 3+ in CaF 2 bismuth borate glass are presented in Table 2. The [24], bismuth borate [25], lead borate glass (PbB) [23], alkali barium-bismuth-tellurite glass (LKBBT) [26] and Li 2 O-MO-B 2 O 3 (LiMB) [27] but is close to those in CaO-Li 2 O-15B 2 O 3 -BaO (CaLBBa) [28].…”

Correlation among electronic polarizability, optical basicity and interaction parameter of Bi2O3–B2O3 glasses

“…On the other hand, oxide glasses are stable hosts for obtaining efficient luminescence in rare-earth ions [7][8][9]. In recent years, heavy metal oxide glasses catch much attention because of their maximum phonon energy [10][11][12][13]. In as much as the emission quantum efficiency from a given level depends strongly on the phonon energy of the host medium, it can be expected that the nonradiative loss to the lattice will be small and the fluorescence quantum efficiency will be high in heavy metal oxide glasses.…”
