摘　　要：合成了一种具有聚合活性的含铽配合物单体 (Tb(acac) 2 (AA)phen) ,并用红外光谱、元素分析等进行表征 .研制了结构为ITO/PVK/Tb(acac) 2 (AA)phen/Alq3/Al的电致发光器件并测定了它的电致发光谱、电流 -电压特性、亮度 -电压曲线等性能 .该器件具有良好的整流特性 ,其电致发光显示了铽离子的绿光特征发射 ,并具有较好的单色性 .同时 。A Tb - containing monomer, terbium - acrylate complex, has been synthesized and characterized by FTIR, EA and UV. Multi - layer electroluminescent (EL) device of the structure ITO/Tb - containing monomwer/Alq(3)/Al was fabricated. The device exhibited characteristic green electroluminescence of the Tb3+ at 550nm at a turn - on voltage of about 24V. The EL spectrum, current - voltage and emission intensity - voltage characteristics of the device were measured and the EL machanism of the device was also discussed. The device also showed good operating and storage stability in ambient conditions.
