Luminescence enhancement of the Tb(III) ion with the thenoyltrifluoroacetonate ligand acting as an efficient sensitizer

Repurposing the Strontium Ranelate Antiosteoporotic Drug as a New Outstanding Biocompatible Blue Dye

“…When excited at this wavelength, it is possible to see the sharp peak of Tb 3+ . This is the energetic level that transfer energy to the metallic center, and this ion emits in agreement with the energy levels of the Tb 3+ ions [17][18][19] shown in Figure 5. As shown in Figure 7C, it is possible to see that, in every case, the emission of the pigment, when excited at 360 nm, is partially quenched.…”

Lanthanide phosphine oxide complexes

“…12. The structures of compounds (59)- (65). which all three CMPO arms bind to the metal in a bidentate manner [133].…”

“…It was found that mole ratios of Nd:(61) of 1:3 were most effective for extraction whilst 1:1 or 1:2 ratios of Nd:(62) were effective for the tetraphosphine oxide. The triphosphine oxides (63) and (64) (65)], the process reaching an equilibrium conversion of about 80% after 120 h. Incorporation of (65) into a polymer film was found to have potential as a luminescent probe for the detection of europium in aqueous solution. An NMR study of CMPO substituted calix [4]arene derivatives coordinate with lanthanide perchlorates differently depending on whether the phosphine oxide is attached to the wide or narrow rim [137].…”

Experimental and theoretical investigations of the [Ln(β-dik)(NO3)2(phen)2]⋅H2O luminescent complexes

“…Despite the growing interest of intramolecular ligand-to-metal energy transfer in this kind of complexes, there have been only a few detailed studies reporting on the spectroscopic properties of the europium mixed ligand complexes that present only one βdiketonate ligand coordinated. Previous reports had been concerned mainly on the structural and luminescent properties of Tb 3+ complexes [13][14][15]. Moreover, no theoretical or experimental investigations have focused on the role of the LMCT state in the quarternary or quinternary mixed ligand complexes, except by our research group on the luminescent properties of the [Eu(dpm)2(NO3)(tppo)2] complexes [16].…”
