摘要
The coprecipitate Tb 0.5 Eu 0.5 3phen was synthesized. By doping the rare earth complex into polymer PVK, the EL device was fabricated with the structure of ITO/PVK∶RE/PBD/Al. Compared with the device using PVK/Eu(asprin) 3phen blend as the light emitting layer, the emission of Eu 3+ in the PVK/Tb 0.5 Eu 0.5 (asprin) 3 phen blend is greatly enhanced along with the quenching of the emission of PVK.
