Enhanced luminescence of Eu3+ by Gd3+ in ternary chelate doped in gel glasses via in situ technique

Luminescent properties of complexes Y1−xEux(TTA)3(TPPO)2 in nano-TiO2

“…The IR spectra of doped complexes are obviously different from that of ligands TTA and TPPO, but are identical with Eu(TTA) 3 (TPPO) 2 complex. This indicates that the Y 1−x Eu x (TTA) 3 (TPPO) 2 complexes are similar to the complexes reported before [10]. The compositions of the complexes were confirmed by elemental analysis.…”

“…Therefore, many rare earth complexes have been synthesized and used as the emitters in photoluminescence and electroluminescence devices [5][6][7][8][9][10]. It is an effective method to improve the luminescence intensity of lanthanide complex by using inorganic semiconductor materials ZnS and TiO 2 [11][12][13][14][15][16].…”

Luminescence properties of complex Tb0.25Eu0.75(TTA)2(N-HPA)Phen

“…Symmetric and asymmetric vibration of -COO − (N-HPA) group peaks was detected at about 1577 and 1413 cm −1 .IR spectra of doping elements complex was obviously different from HTTA, N-HPA and 1,10-phenanthroline ligands. This indicates that were similar to the complex reported before[11,12].…”

Polylactide/poly(butylene adipate‐co‐terephthalate)/rare earth complexes as biodegradable light conversion agricultural films

“…The stretching vibration of P═O at 1190 cm −1 belongs to the second ligand of TPPO, and the peak moves to 1061 cm −1 after forming coordination bonds with Eu 3+ . The peak at 535 cm −1 belongs to Eu─O stretching vibration, which marks the formation of the complex …”
