One new La (III) based coordination polymer , namely, [La(1,4-bdc)(H2O)].(H2O) (1) (tpa = terephthalic acid) has been synthesized through the solvothermal synthesis using terephthalic acid. Structural analysis reveals that compound 1 has a 3-D network with a cube topology. The solid state photolumienescence study shows that compound 1 has a strong emission peak at 680 nm upon excitation at 220 nm . The emission peak is characteristic of the red light emission in the visible region of the electromagnetic spectrum.

Visible luminescence of Pr3+ ions in bismuth borate glasses doped with difference concentration of Pr2O3 have been studies. The glasses of composition 30Bi2O3 : (70-x)B2O3 : xPr2O3 (where x = 0.0, 0.5, 1.0, 1.5, 2.0 and 2.5 mol%) were prepared by the melt quenching technique. The spectral properties were investigated using the absorption and emission measurement. These glasses have shown emission and excitation bands in visible region. The emission band of Pr3+ doped glass centered at 600 nm (1D23H4), 642 nm (3P03F2) and 704 nm (3P03F3) have been observed with 469 nm (3H43P1) excitation wavelength. The excitation band revealed centered at 447, 469 and 482 nm corresponding to the 3H43P2, 3P1 and 3P0 transitions, respectively.

A new lanthanide pyridine-2,4,6-tricarboxylato coordination polymer, [Dy2(H2O)5(ptc)2]·H2O (H3ptc = pyridine-2,4,6-tricarboxylic acid), was hydrothermally synthesized. The complex exhibits both mono-capped square antiprismatic DyNO8 chromophores and 4,4ʹ-bicapped trigonal prismatic DyNO7 chromophores, which are interconnected through ptc3− anions in μ3η6 and μ4η6 coordination modes to achieve a new 3D MOF of an unprecedented topology of (4 · 63 · 82)(63) type. This Dy(III) complex exhibits a characteristic luminescence in the visible region upon excitation at 300 nm. The temperature-dependent magnetic properties of the Dy(III) complex were investigated in the temperature range of 2 - 300 K.

Important Approach

ABSTRACTOrganic electroluminescent (EL) diodes based on fluorescent dyes and conducting polymers have attracted the interest of researchers, mainly because of their emission in the visible region and for application to large area portable flat panel display devices, driven at low voltages. Therefore, for the development of higher efficiency polymer EL diodes, the optimal combination of the merits of organic fluorescent dye molecules with that of conjugated polymer is an important approach. We report electroluminescence studies of polymer light emitting diodes (p-LEDs) fabricated with poly[2-(3-thienyl)ethanol n-butoxy carbonylmethyl urethane] (PURET) and its composite with 4-dicyanomethylene-2-methyl-6-(p-dimethylaminostyryl)-4H pyran (DCM) dye. These materials have been chosen in view of the fact that PURET exhibits a small overlap between emission and absorption spectra whereas DCM has a good efficiency of trapping both electrons as well as holes. Polyaniline has been utilized as hole injecting layer whereas tris-8-hydroxyquinoline-aluminum as electron injecting layer. Enhanced electroluminescence with bright yellow color has been observed in p-LEDs by the addition of dye.
