Synthesis and Characterization of Europium Ternary Luminescence Coordination Compound Nanorods

Abstract:

Ternary luminescence coordination compound nanorods composed of rare-earth (Eu(III))- trimesic acid (TMA)-1.10-phenanthroline (phen) were synthesized in alcohol and water mixed solvent. The chemical composition of the obtained sample deduced from the elemental analysis, plasma atomic emission spectra and infrared spectra is Eu (MTA)(phen)·10H2O. Thermal analysis (TG-DTA) showed that the coordination compound has better stability under 463°C, and the decomposition mechanics is Eu (MTA) (phen)·10H2O→Eu (MTA) (phen)·2H2O→Eu (MTA) (C6H6N2)→ Eu2O3. XRD patterns showed that the obtained coordination compound is a new crystal different from that of two ligands. TEM image indicated that coordination compound is nanorods with better dispersity. The diameter of nanorods is about 50~100 nm and the length ranges from hundred nanometer to a few micrometers. Photoluminescence analysis indicated that the coordination compound emits Eu3+ characteristic luminescence under ultraviolet excitation.
