Abstract

A new rare earth complex Tb(BSA)4 was synthesized and studied. Pure green and narrow band emission was generated from the device with structure ITO/PVK:Tb(BSA)4 /Alq3 /LiF/Al, where PVK was used to improve the film-formation and hole-transport property of the Tb(BSA)4. The absorption mechanism, and the photoluminescence and electroluminescence mechanisms are discussed. It has been proved that there exists energy transfer from PVK to Tb(BSA)4 and the mechanisms of photoluminescence and electroluminescence are different. The effect of different ratios of PVK on the device characteristics is also studied.

摘要

合成并研究了一种新型稀土配合物Tb(BSA)4。结构为ITO/PVK:Tb(BSA)4 /Alq3 /LiF/Al的器件产生了纯绿色窄带发射，其中PVK用于改善Tb(BSA)4的成膜和空穴传输性能。讨论了吸收机制、光致发光和电致发光机制。已证明存在从PVK到Tb(BSA)4的能量转移，且光致发光和电致发光机制不同。还研究了不同PVK比例对器件特性的影响。
