Simulation of Eu3+ luminescence spectra of borosilicate glasses by molecular dynamics calculations

Effect of boron oxide addition on the Nd3+ environment in a Nd-rich soda-lime aluminoborosilicate glass

“…No evidence is found of a welldefined order like in Nd-metaborate crystals. These findings are in agreement with a study of Eu 3+ environment in similar aluminoborosilicate glasses using fluorescence spectroscopy and molecular dynamics simulations, that showed that the majority of Eu 3+ ions entered a borate-silicate mixed environment [38].…”

β-Irradiation Effects on the Formation and Stability of CaMoO4 in a Soda Lime Borosilicate Glass Ceramic for Nuclear Waste Storage

“…In fully amorphous CNO (Figure 9) there are several broad bands at ∼450−520 cm −1 (Si−O−Si bending), 45,46 42,46 ), ∼1445 cm −1 (B−O − bond elongation in metaborate chains and rings 46 ), and Si−O stretching vibration for Q n entities that represent SiO 4 units with n bridging oxygen between 845− 1256 cm −1 (Figure 9). The effects of adding 1 mol % MoO 3 to a soda lime borosilicate glass can be observed in Figure 9.…”

Optical properties of Eu3+ in transparent Y–Ti–O nanocrystallized sol–gel film

“…The main emission peaks at 612, 617 and 626 nm are due to the 5 D 0 → 7 F 2 transition of Eu 3+ in C 2 site in the cubic structure, which has relatively poor inversion symmetry [23]. Other less prominent emission peaks near 595, 650, and 706 nm are due to the transitions from the 5 D 0 state to the 7 F 1 , 7 F 3 , and 7 F 4 states, respectively [24,25]. Strong splittings of the 5 D 0 → 7 F 1 and the 5 D 0 → 7 F 2 transitions indicate that the inconsistent structural environments exist around the Eu 3+ ions, which are different from the cases in amorphous hosts [26].…”
