摘要
选用β-二酮配体苯甲酰丙酮(BZA)作为第一配体,再选用适当的协同配体邻菲咯啉(Phen),掺杂惰性稀土离子钆(Gd3+),合成了EuxGd(1-x)(BZA)3Phen红色荧光剂。通过元素组成、红外光谱、紫外光谱、热性能、荧光性能对其进行了表征,并研究了该掺杂配合物体系的发光机理,利用分子间能量传递模式解释了惰性稀土离子对EuxGd(1-x)(BZA)3Phen的"共发光效应"。结果表明,这是一类性能优良、成本较低的铕配合物。
Red fluorescent agent Eux Gd（1-x） （BZA）3 Phen were synthesized by using low cost, good stability β- diketones ligands benzoylacetone （BZA） as the first ligand, and phenanthroline （Phen） as appropriate synergistic ligand, and doped inert rare earth ions gadolinium（Gd^3＋ ）. The agent was characterized by elemental composition, IR, UV spectra, thermal properties, and fluorescence properties. The light-emitting mechanism of doped complex was studied. The inert rare earth ions co-fluorescence effect on Eux Gd（1-x） （BZA）3 Phen was explained by intermoleeular energy transfer model. The results showed that this is an excellent performance and low cost europium complex.
