中文摘要
本論文主要研究高分子磷光發光二極體(Polymer Phosphorescent light-emitting diodes, PPLEDs)之能量轉移現象。研究主要分為三部分:新型主體高分子摻雜磷光材料之元件、主體高分子PVK 摻雜磷光材料元件,以及新型磷光高分子發光元件。
首先我們研究新型主體高分子BP105(Polyfluorene-based material)摻雜磷光染料Ir(ppy)3 之能量轉移現象。接著使用PVK 做為主體高分子材料,摻雜磷光染料Ir(ppy)3、FIrpic,觀察其是否能有效改善能量轉移效率。最後研究新型主體高分子與磷光材料分別採用混和(Blend)與化學鍵結(Bonding)方式製作之元件,並針對元件效率與能量轉移效率作比較。
另外本論文藉由添加glycerol提升導電高分子PEDOT:PSS導電度,並將其應用在螢光高分子super yellow 元件中,針對其元件效率與製程變化作比較。實驗結果發現:使用改質過後PEDOT:PSS所製作之PLED元件,電流密度與發光效率皆大幅改善。
Abstract
In this research, we studied the phenomenon of energy transfer of polymer phosphorescent light-emitting diodes, PPLEDs. This thesis was divided into three parts: devices constructed by new-type host polymer blended with phosphorescent material, devices constructed by host polymer PVK blended with phosphorescent materials, and devices constructed by new-type phosphorescent polymer materials.
The phenomenon of energy transfer between host polymer BP105 and phosphorescent dye Ir(ppy)3 was studied. Second, we chose PVK as a host polymer material, and Ir(ppy)3 as a phosphorescent guest material, to observe whether it can improve efficiency of devices by using energy transfer process. At last we manufactured devices constructed by new-type host polymer blended or bonded with new-type phosphorescent materials, and compared their emitting and energy transfer efficiency.
A glycerol-modified PEDOT:PSS layer that used as an anode buffer layer in PLED using super yellow as the emitter was also been studied. It was found the glycerol-modified device showed a larger current density and improved luminescent efficiency then that of the unmodified device.
