Designing and Judd-Ofelt evaluation of versatile luminescent Eu (III) complexes sensitized with β-diketone ligand for multifarious applications.

The present research work entails the synthesis of one binary and four ternary red light-emitting Eu (III)-based complexes with 3-benzylidene-2,4-pentanedione as the main ligand and 1,10-phenanthroline, bathophenanthroline, neocuproine, and 4,4'-'dimethyl-2,2'-'bipyridyl as auxiliary ligands. The metal-organic framework of the series was elucidated using energy dispersive X-ray analysis, elemental analysis, Fourier transform infrared spectroscopy, and proton nuclear magnetic resonance. This Eu (III) series exhibits optimum thermal stability, making them a promising candidate for organic light-emitting diodes.

Structural Insights and Photophysical Screening of Sm (III) Complexes with Heterocyclic Ligand for Optical Applications.

Five novel bright orange color emitting Sm(III) complexes (C1-C5) have been synthesized via energy efficient and cost effective solution precipitation method with 5-phenyl 2-furoic acid as primary organic sensitizer and nitrogen donor neocuproine, 2, 2- bipyridyl, bathophenanthroline, and 1,10-phenanthroline as secondary ligands. All the newly synthesized metal complexes are thoroughly characterize to examine the appropriateness of the organic ligand for the sensitization process. All the outcomes of the various advanced and fundamental spectroscopic techniques validate the bonding of carboxylate group with the Sm(III) ion.

Investigations into spectroscopic and optoelectronic behaviour of furoic acid-based Eu(III) complexes for advanced photonic applications.

To illuminate the zone of organic light-emitting diodes, a novel series of four red luminescent europium complexes, one binary (C1) and three ternary (C2-C4), of 5-phenyl 2-furoic acid was synthesized with 2,2'-bipyridyl (bipy), bathophenanthroline (batho) and 1,10-phenanthroline (phen) as ancillary ligands and characterized by adopting various analytical techniques. All the findings of energy-dispersive X-ray spectroscopy, elemental (CHN) analysis, Fourier transform infrared, nuclear magnetic resonance, and ultraviolet-visible spectroscopy confirmed the coordination of ligand binding sites with the europium ion. To evaluate the thermal stability, thermogravimetric/difference thermogravimetric measurements were taken that revealed that the synthesized complexes were stable up to 245°C.

New Insights into Optoelectronic Features of Eu(III) Complexes with Heterocyclic Ligand for Advanced Optical Applications.

Our present technological society needs the assistance of lanthanide luminescence in almost every field to meet the global energy demands. In present research work we have synthesized five (one binary and four ternary) 5-(4-methylphenyl)-2- furoic acid based Eu(III) complexes with ancillary ligands, namely, aqua (HO), neocuproine (neo), 2, 2'-bipyridyl (bipy), bathophenanthroline (batho) and 1, 10-phenanthroline (phen). The spectroscopic analysis and photophysical features are characterized by the use of different investigative techniques.
