【摘要】合成了一类以苯甲酰水杨酸(benzoylsalicylicacid,BSA)为第一配体,邻菲罗啉(1,10 phenanthroline,phen)为第二配体的稀土铽配合物,将导电高分子材料PVK引入到配合物中,制成了结构为ITO PVK:Tb(BSA)3phen PBD Alq LiF Al电致发光器件。并对该配合物的吸收特性及电致发光和光致发光性能进行了研究,实验数据表明在PVK与Tb(BSA)3phen之间存在着Forster能量传递.该配合物具有很好的光致发光和电致发光性能。本文同时比较了几种不同PVK掺杂浓度对于器件性能的影响。更多还原

【Abstract】 A new rare earth complex Tb(BSA)3phen was synthesized and studied. Pure green and narrow band emission from the device of structure ITO/PVK: Tb(BSA)3phen/PBD/Alq/LiF/Al, where PVK was used to improve the filmforming and holetransporting property of the Tb(BSA)3phen. The absorption mechanism and photoluminescence and electroluminescence mechanism are discussed. It has been proved that there exists Forster energy transfer process from PVK to Tb(BSA)3phen. This new material has good photoluminescent and electroluminescent property. The effect of the different ratio of PVK on device charncteristics is also studied.更多还原
