| 摘 要： | 选用苯甲酸(BA)、噻吩甲酰三氟丙酮(TTA)、邻菲咯啉(Phen)作为配体合成了Eu(BA)3Phen三元配合物、Eu(BA)(TTA)2Phen四元配合物,将其作为荧光剂,制备了稀土荧光防伪油墨。红外光谱的分析表明配体与铕离子发生了配位。测定了配合物和荧光防伪油墨的荧光性能,发射波长为614 nm,制备的稀土荧光防伪油墨在可见光下印迹无色,在紫外灯下呈现明显红色荧光。

| Abstract: | Ternary europium complex Eu(BA)3Phen and quaternary europium complex Eu(BA)(TTA)2Phen were synthesized with ligands of benzoic acid,α-thenoyltrifluoroacetone(TTA),and o-phenanthroline.Rare earths fluorescent falsification-resistant ink was prepared with the synthesized fluorescent agents.IR spectrum analysis showed that these complexes collocate with Eu ions.Luminescence properties of the inks and the complexes were determined.The results showed that the emission wavelength is 614 nm;the ink is invisible under visible light,and appears red under UV light. |
