稀土铽三元有机配合物合成及荧光性能研究

Synthesized on organic ternary complexes of terbium & investment on the fluorescence

合成了7种铽的稀土荧光有机材料——铽三元有机配合物,通过荧光光谱的测定,比较了第一配体的改变对配合物发光性能,尤其是发光强度的影响。实验表明,在以邻菲啉为第二配体的情况下,第一配体对铽三元配合物荧光强度影响顺序依次是:磺基水杨酸>对甲基苯甲酸>水杨酸>苯甲酸>对氨基苯甲酸>乙酰丙酮,其磺基水杨酸为第一配体的铽三元有机配合物荧光强度最大,其相对强度为20000。

In this paper,seven organic fluorescence materials of rare-earth terbium complex organic ternary complexes of terbium was synthesized.Determination by fluorescence spectroscopy and complex luminescent properties,especially the luminous intensity,was compared with the first ligand changed.Experiments results showed that in the case of phenanthroline as the second ligand,the first ligand influences the luminous intensity of terbium ternary complexes： sulfosalicylic acid〉p-toluic acid 〉salicylic acid 〉benzoic acid〉 p-aminobenzoic acid 〉acetylacetone.Terbium organic ternary complexes luminous intensity was the strongest when sulfosalicylic acid was the firsfirst ligand.Its relative strength was 20000.The rare-earth terbium organic ternary complexes was used in UV-curalble ink and the luminous intensity was investigated.
