Theoretical insight in highly luminescent properties of Eu(III) complex with phenanthroline

Luminescent Complexes of Europium (III) with 2-(Phenylethynyl)-1,10-phenanthroline: The Role of the Counterions

“…The phenanthroline and its derivatives are known for being ligands for different metal ions as well as effective photosensitizers of lanthanoids [ 27 ]. Therefore, a number of europium (III) complexes with phenanthroline-based antenna have been reported recently [ 29 , 30 , 31 ]. Since the antenna effect is extremely interesting from fundamental point of view, many theoretical and spectroscopic studies discussed the photophysical process of absorption of light, the excited state energy transfer from the ligand to the europium ion and the luminescent properties of these compounds [ 30 , 31 , 32 , 33 , 34 ].…”

Monochromatic red electroluminescence from a homodinuclear europium(iii) complex of a β-diketone tethered by 2,2′-bipyrimidine

“…In addition for the CAM-B3LYP and LC-BLYP range-separated hybrid functionals, the spectra obtained from the B3LYP geometry are almost similar. Although Georgieva and coworkers 21 have shown that the best functional for describing the absorption of [Eu(phen) 2 (NO 3 ) 3 ] complex is the PBE1PBE hybrid functional, for the complex studied here, PBE1PBE provided a spectrum that is substantially shifted for large values of wavelengths. Interestingly, INDO/S-CIS semiempirical model predicts the best result among all (Fig.…”

Highly luminescent mixed-ligand bimetallic lanthanoid(iii) complexes for photovoltaic applications

“…The excited singletstate energies of the ligands take values of 44.000 cm −1 , 37.000 cm −1 , and 28.900 cm −1 for benzoate, phen, and tta − respectively, corresponding with those previously reported. 67,68 Solid-state room-temperature photoluminescence. Photoluminescence emission spectra (λ exc = 350 nm) of the Eu 3+ containing complexes (1,(3)(4)(5)(6) are shown in Fig.…”
