| 中文摘要: |
| 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Eu-xGd-(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Eu-xGd-(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。 |
| 英文摘要: |
| Red fluorescent agent Eu-xGd-(1-x)(BZA)-3Phen 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(Gd3+). 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 Eu-xGd-(1-x)(BZA)-3Phen was explained by intermolecular energy transfer model. The results showed that this is an excellent performance and low cost europium complex. |
