Carboxylato-bis-dibenzoylmethanates of europium(III): Luminescence and magnetic properties

“…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].…”

Люминесцентные свойства разнолигандных beta-дикетонатов неодима, полученных в среде сверхкритического диоксида углерода в полимерных матрицах различной природы

“…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].…”

Organosilicon Amidophosphates and Their Eu and Er Complexes in Solutions and Films: Spectral and Luminescence Properties

“…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].…”
