Dhankhar, Priyanka published the artcilePhotoluminescent report on red light emitting europium(III) complexes with heterocyclic acid, Category: pyrazoles-derivatives, the publication is Spectroscopy Letters (2020), 53(4), 256-269, database is CAplus.
Five luminescent europium (III) carboxylate complexes have been synthesized by using ligand 3-isopropylpyrazole-5-carboxylic acid as primary ligand and 4,4′-dimethyl-2,2′-bipyridyl, 2,2′-bipyridyl, 5,6-dimethyl-1,10-phenanthroline and 1,10-phenanthroline as secondary ligands and characterized through various techniques. These complexes exhibit excellent thermal stability and characteristic europium centered photoemission spectra under the excitation of UV light. Luminescence decay curves, Judd-Ofelt anal., internal quantum efficiency and energy transfer mechanism have also been discussed. The color coordinates and color purity are calculated to investigate red emission of the complexes. The study results reveal that these complexes can be potentially used as red light emitting materials in various optoelectronic devices.
