合成了以苯甲酰丙酮为第一配体,1,10-邻菲哆啉为第二配体的一种铽的三元配合物Tb(BAC)3Phen,通过元素分析确定了其组成,并用红外吸收光谱、紫外。可见光吸收光谱、差热-热重曲线、原子力显微镜对其进行了表征,同时研究了Tb(BAC)3Phen的光致发光性能。实验结果表明配体苯甲酰丙酮和1,10-邻菲哆啉能够较好地敏化中心离子Tb^3-发光,Tb(BAC)3Phen的最大发射波长为615nm,并具有良好的热稳定性和成膜性,是一种黄白光发光材料。
A terbium complex Tb(BAC)3Phen using benzoylacetone(BAC) as the first ligand and 1,10-phenanthroline (Phen) as the second ligand was synthesized. Elemental analysis, IR, UV-Vis spectrum analysis were carded out with the complex. The thermal and photoluminescence properties were measured. The results indicated that the complex had a good thermal stability and it was a yellow-emitting material. Meanwhile, the energy-transfer between the ligands and Tb^3+ ions was proved to be effective. Besides, observerd under the AFM, the complex had good property for filming. All indicated that the complex was a good kind of rare-earth electroluminescent materials.
