Synthesis, Characterization and Property of Nano Rare Earth Terbium Complex with Gatifloxacin

Rare earth metal complexes have special characteristics, such as extremely narrow emission bands and high internal quantum efficiencies, which are suitable to be used as the emission materials, chemistry and biological technology. Ternary nano complex of terbium gatifloxacin phenanthroline was synthesized.The composition and structure of ternary complex were characterized by element analysis, Mass Spectrometry (MS), UltraViolet Absorption Spectrometry (UV) and fluorescence spectra(FS). The influences of solubility, thermal stability and luminescent properties of complex as well as addition of phenanthroline secondary ligands on the fluorescence spectra of the ternary complexes were studied. The results of fluorescence spectra analysis showed that partial energy was transferred from Characterization to terbium ions by intramolecular energy transfer processes, meanwhile, the addition of phenanthroline can effectively increase the luminescence intensity of terbium icons. The complex possessed well luminescence and showed characteristic emission peaks of Tb3+ under UV light excitation and emitted strong green fluorescence. Moreover, in an ITO/PVK/Tb(GFLX)3Phen/Al device, Tb3+ ion can be excited by intramolecular ligand-to-metal energy transfer process. The main peak of emission at 545 nm is attributed to 5D0→7F2 transition of the Tb3+ ion, and this process results in the enhancing green emission. Biological actrivity properties of the rare earth complex was well studied.

ABSTRACTWe investigated luminescent properties of rare-earth metal complexes and phosphor-rescent molecules doped in a conducting polymer. Electroluminescent (EL) properties in combination of red emissive europium complex of tris(di-benzoylmethane)-mono(4,7-diphenyl-phenanthroline) europium (III) (Eu(dbm)3phen) and blue phosphorescent molecule of bis[(4,6-difluoro-phenyl)-pyridinato-N,C2'] (picolinate) iridium (III) (FIrpic) doped in poly(N-vinyl-carbazole) (PVK) and a new rare-earth complex tris(hexafluoroacethylacetonato) (phenan-throline) samarium(III) [Sm(hfa)3(phen)2] have been investigated as an EL emitter. White EL has been obtained from mixed layer of Eu(dbm)3phen and FIrpic, and EL from Sm complex has been obtained. Energy transfer and the emission mechanisms have been discussed.

The Rare Earth

A UV-cured composite containing a rare earth complex was prepared for this study. First, the photoluminescent terbium complex was synthesized with a long-chain unsaturated fatty acid (10-Undecenoic acid) by a solution precipitation method, resulting in the 10-UA-Tb(III) complex. Its structure was proven by FTIR, elemental analysis, XRD, and TGA. The results indicated that the organic acid ligand successfully coordinated with the Tb3+ ion and that the complex had a chelate bidentate structure. The emission spectrum of the 10-UA-Tb(III) complex indicated that the complex can emit a bright green light with the unique luminescence of the Tb3+ ion. Furthermore, the luminescence properties of complexes with different ratios of Tb3+ and ligand were studied, and the ratio of Tb3+ and the ligand had an obvious impact on the luminescence intensity of the 10-UA-Tb(III) complex. Subsequently, the prepared rare earth complex was doped into a UV-cured coating in different proportions to obtain a UV-cured composite. The morphology of the rare earth UV-cured composite was observed by SEM. The images showed that the rare earth complex was dispersed uniformly in the polymer matrix. Moreover, the composites could emit fluorescence. Additionally, it has good thermal stability and compatibility with the resin. Therefore, these composites should have potential applications in UV curable materials, such as luminescence coatings.

Rare earth phosphors of Ca0.85(W1-xMox)O4:Eu0.15 (x=0.00-0.50) were synthesized via solidstate reaction in air. The lattice parameters strongly depended on the x value, which was analyzed by the XRD patterns. Microstructures of the powders were observed by SEM. The phosphors could be effectively excitated by ultraviolet (UV) light (250-300nm) and blue light (464nm), which were showed with the excitation and emission spectra. With the increasing of x value, moreover, another emission peak of the sample which was excitated by UV light appeared and shifted to short wavelength, from 597 to 545 nm. The luminescence properties of the phosphors and energy transfer mechanism were also discussed.

Rare earth complex Eu(phen)2Cl3·2H2O synthesized by precipitation method was incorporated into MCM-41 mesoporous molecular sieves which were synthesized via a hydrothermal method. Hybrid inorganic/organic mesoporous luminescent material Eu(phen)2/MCM-41 has been characterized by XRD, TEM, IR, UV-visible spectra and fluorescence spectra. Results indicated that the hybrid mesoporous material has typical structure of MCM-41 and retains the same pore structure as MCM-41 after the assembly process. The fluorescence spectra of these materials present a series of narrow lines assigned to 5D0 → 7F0,1,2,3,4 transitions. The high emission intensity observed is a promising property for application of the rare earth complex in technological luminescent devices.
