ternary terbium complexes based on fluorinated ligand 4,4,4-trifluoro-1-(2-naphthyl)-1,3-butanedione (TFNB) and other auxiliary ligands were synthesized and explored. Optical and photophysical characteristics of complexes were examined spectroscopically. Thermal and electrochemical behavior of complexes is also reported. In emission spectra of complexes, four characteristic peaks of Tb3+ ion at 492 nm,
合成并探索了一系列基于氟化配体4,4,4-三氟-1-(2-萘基)-1,3-丁二酮(TFNB)和其他辅助配体的发光三元铽配合物。用光谱法检查配合物的光学和光物理特性。还报道了配合物的热和电化学行为。在配合物的发射光谱中,Tb 3+离子在 492 nm、548 nm、586 nm 和 615 nm 处的四个特征峰被鉴定为5 D 4 → 7 F J(J = 6-3) 跃迁在紫外区激发时出现。548 nm 处的最强峰是三元配合物发出亮绿色的原因。颜色纯度和 CIE 参数也表明配合物的绿色发光行为。我们的研究表明,合成的配合物由于其发光特性可用于制备照明系统、OLED 和显示设备。
