A new β-diketone complex with high color purity

Structure and photophysics of a europium dimeric system, Eu2(HFAA)2(Dipy)2(TFOAc)2(OAc)2, in the solid state and solution

“…Among several applications of lanthanides compounds very important role is played by optical techniques [1][2][3][4][5][6]. The design of the rare earth ions complexes-efficient emitters has become a widely research goal.…”

“…Among different classes of organic ligands, ␤-diketones play very important role both in single crystals as well as incorporated into silica matrices. The lanthanide ␤-diketones may find several applications as luminescent labels in fluoroimmunoassays, NMR shifts reagents, laser materials and luminescent diodes [1][2][3][4][5][6][7][8][9][10].…”

Judd–Ofelt treatment on luminescence of europium complexes with β-diketone and bis(β-diketone)

“…The CIE chromaticity coordinates calculated from Fig. 4 (b) (l ex ¼ 413 nm) are x ¼ 0.637 and y ¼ 0.343, this result shows red color purity around 100% in the CIE gamut color space [36], indicating that the red emission of Eu 2 (DDBM) 3 H 2 O exhibits monochromatic color [37].…”

Langmuir–Blodgett films incorporating an ionic europium complex

“…[13], the purity and structure of the complex was confirmed by elemental analyses and spectroscopic characterizations. The molecular structure bmdm ligand (1-(4-methoxyphenyl)-3-(4-tert-butylphenyl)propane-1,3-dione) was shown in Fig.…”

“…In our previous work the synthesis and characterization of NH 4 [Eu(bmdm) 4 ] was described [13]. Melby et al [14] described tetrakis diketonates as potassium and sodium salts.…”
