“…carboxylato bis dibenzoylmethanates containing Eu(Dbm) 2 Acid, where Dbm is dibenzoyl methane, and Acid is formic (Form), butyric (But), hexanoic (Hex), trifluoroacetic (TFAc), cinnamic (Cin), and β piperonylacrylic (β pipacr) acids, were obtained by the method described in [3] via the inter action of equimolar quantities of Eu(NO 3 ) 3 ⋅ 6H 2 O, dibenzoylmethane, and the corresponding acid in ethanol, followed by neutralization of the solution with ammonia.…”

“…Europium compounds based on carboxylic acids can be divided into two groups: those with normal and anomalous Stark structures of their luminescence spectra, for which an extraordinarily high relative intensity of the band of singlet transition 5 D 0 -7 F 0 is typical, while the 7 F 1 level nearest to the ground state is arranged unusually close (~175 cm -1 ) [1][2][3].…”

“…The anomalous Stark structure of luminescence spectra of europium carboxylatodibenzoylmetha nates and the temperature behavior of their lumines cence [1][2][3] led to the search for correlations between the luminescent and magnetic characteris tics of these compounds. This work is a continuation of our investigation of the luminescent and magnetic characteristics of europium(III) compounds with anomalous and normal structures of their lumines cence spectra [4].…”

“…Одной из проблем, возникающих при получении полимеров, допированных металлокомплексами, является гомогенность и равномерность распределения их в полимерной матрице, обеспечивающая высокую эффективность преобразования УФ излучения. Одним из методов получения полимеров, обеспечивающих гомогенность распределения РЗЭ, является соответствующая модификация мономеров с последующей их гомо-или сополимеризацией [7]. Однако процесс полимеризации (выбор метода и инициирующего воздействия) довольно сложен и должен проводиться с учётом специфики строения и свойств металлсодержащих мономеров [8].…”

Multi-ligand phosphor complexes of neodymium acetylacetonate with phenanthroline are synthesized in polymer matrices (oligourethane methacrylate, fluoroplast, polycarbonate) in supercritical carbon dioxide medium. At the same time the role of one of the ligands in such complexes is played by fragments of the polymer matrix. The luminescence spectra of the obtained ternary systems are described. It was shown that the position of the luminescence maxima is bathochromically shifted relative to the binary systems Nd(Acac)3/polymer obtained in a similar way and the magnitude of the shift depends on the nature of the polymer matrix. It was shown that upon the introduction of these components into polymers from a solution, similar phosphor mixed-ligand neodymium complexes do not form. The formation of new structures Nd(Acac)3/Phen/polymer upon impregnation of oligourethane methacrylate with neodymium β-diketonate and phenanthroline in a supercritical CO2 medium was confirmed by the method of differential thermal analysis. The same method confirmed that with the introduction of these components from the solution of the above systems do not form.

“…The data are available in the literature on doping by Eu and some other lanthanides of fluoroorganic polymers [2], acryl polymers [6][7][8], polyurethane urea [9], siloxane polyethyleneglycole nanohybrids [10,11], solidified esters of phosphorus acids [12], amorphous oxides of silicon [13] and aluminium [14], organosiloxane-oxide hybrids [15][16][17][18][19]. The increased emission of Nd(III) bis(perfluoromethanosulfonyl)aminate in zeolite cavity was observed in [20].…”

International audienceFluorescence and fluorescence excitation spectra of phosphorus-containing organosilicon ligands O = PX2NHR (X = NMe2, OPh; R = CH2CH2CH2Si(Oet)3 and their Eu(III) complexes in acetonitrile solutions and in films are studied. In UV region (285–420 nm), bis(dimethylamido)triethoxysilylpropylamidophosphate (X = NMe2) and diphenyltriethoxysilylpropylamidophosphate (X = OPh) exhibit two emission bands, whose position and intensity depend on the nature of substituents at the phosphorus atom. The Eu complexes show the ligand and the cation luminescence. The emission bands of coordinated ligands are shifted to long-wave region. The cation luminescence appears as three or four bands due to f-f transitions from the excited 5 D 0 level to the lower 7 F 1–4 levels. The most intense transition is 5 D 0 → 7 F 2. The emission band in a region of 420 nm appears in solutions and films prepared from both pure ligands and their Eu(III) complexes. This band is due to luminescence of spatially crosslinked nanoparticles of sesquioxane structure. The intensity ratio of the Eu3+ emission bands changes when going from solutions to films, the emission intensity increases in a range of 420 nm. Films containing incorporated Er complexes with amidophosphates show intense luminescence of a matrix at 430 nm and a series of weak narrow bands due to the Er3+ cation at 550–700 nm
