| 摘 要： | 用一种新型的含酚羟基的Schiff碱三足配体H3L3稀土Tb配合物作发光层制备了三层结构电致发光器件，器件在正向直流偏压下发出明亮的绿光。器件的电致发光(EL)光谱和Tb配合物薄膜的光致发光(PL)光谱与典型的Tb配合物的发光光谱相同。研究了器件发光及电学特性，讨论了该种新型的稀土Tc配合物的发光机理。

| Abstract: | Pure green and narrowbandwidth emission from an organic electroluminescent device was presented by using arare earth terbium (III) complex as the emissive layer. The structure of the device was ITO/PVK/Tb/PBD/LiF/Al. It was proved that this new kind of rare earth complex has excellent photoluminescent and electroluminescent properties. The electroluminescent spectrum of the device was very similar to that of the terbium (III) complex film. The electroluminescent mechanism of the device was proposed by measuring and analyzing the spectra and electroluminescent property of the device. It is proposed that the excited carriers of PVK and PBD were captured by Tb3+ and light was emitted when the electrons and holes recombined at Tb3+. |
