Room Temperature Synthesis of Samarium Pyrazine-2,3,5,6-tetracarboxylate Coordination Polymers via A Fast Precipitation Method and Their Luminescent Properties
摘要
Abstract
Samarium pyrazine-2 ,3 ,5 ,6-tetracarboxylate coordination polymers with sub-micron ellip-soid-like architecture were successfully synthesized via an efficient direct precipitation method at room temperature. Fourier transform infrared spectra, energy dispersive spectrum, scanning electron microscopy , UV-Vis spectra and photoluminescent spectra were employed to characterize the samari-um pyrazine-2,3,5,6-tetracarboxylate samples. The experimental results indicate that the pH value of the solution has an obvious impact on the morghologies and photoluminescent properties of the samples. The morphology can be easily controlled from nano-size to sub-micron particles by chan-ging the pH value. All the samples show three emission peaks at 563, 598 and 644 nm, which are assigned to the characteristic emission transitions 4 G5/2→6 H5/2 , 4 G5/2→6 H7/2 and 4 G5/2→6 H9/2 of Sm3+ ions. Moreover, the samples synthesized at the pH value of 7 demonstrate the strongest emiss-tion compared with other samples.关键词
