Synthesis and luminescence characteristics of terbium(III) activated NaSrBO3

Enhanced visible light photocatalytic activity of ZnO doped with down-conversion NaSrBO3:Tb3+ phosphors

“…Upon the excitation at 480 nm, the main emission peak is observed at 544 nm, corresponding to the 5 D 4 → 7 F 5 transition of the Tb 3+ ions because the transition has the largest probability for both electric-dipole and magnetic-dipole induced transitions. 45 Fig. 6(b) shows the UV-vis absorption spectra of MB, RhB, and MO.…”

Hybrid lanthanide complexes based on a novel β-diketone functionalized polyhedral oligomeric silsesquioxane (POSS) and their nanocomposites with PMMA via in situ polymerization

“…[54][55][56] Bands in the 400 nm to 650 nm range can be clearly observed in the luminescence spectra of POSS_Tb, which are assigned to 5 D 4 / 7 F 6 , 5 D 4 / 7 F 5 , 5 D 4 / 7 F 4 and 5 D 4 / 7 F 3 transitions of Tb 3+ in POSS_Tb at 491, 546, 586 and 625 nm, respectively. [57][58][59] Consequently, strong and characteristic luminescence were observed in the emission spectra. This nding indicates that effective intramolecular energy transfer occurred between the POSS_dendrimer and the cheated rare earth ions.…”

Synthesis of a novel green fluorescent material Ca3Al2O6:Tb3+ based on a layered double hydroxide precursor

“…Emission spectra show the peaks mainly at 487, 543, 583, and 620 nm, respectively when excited at 266 nm. They are identified as 5 D 4 to 7 F j (j = 6-3) transitions within the 4f 8 configurations Tb 3+ [13] in the Ca 3 Al 2 O 6 phosphors. Among the emission lines from the 5 D 4 state the dominant emission is observed at 543 nm, corresponding to the 5 D 4 → 7 F 5 transition.…”
