One-dimensional (1D) europium coordination polymer wires: Synthesis, characterization and photoluminescence properties

1D europium coordination polymer wires were successfully prepared by reacting europium chloride with tributyl phosphate (TBP) at 160 °C for 12 h. The products were characterized by XRD, IR, TG, DTA, SEM, and EDS. SEM results showed that the wires were with diameters ranging from several hundreds of nanometers to ∼5 μm and lengths going up to several hundreds of micrometers. Influencing factors such as the dosage of reactants and reaction time on the preparation were systematically investigated. Strong emission centering at 590 nm was realized in the coordination polymer wires on excitation at 395 nm.
