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.
