Abstract：The present work investigates the photoluminescence (PL) and electroluminescence (EL) characteristics of Eu-complex Eu(UVA)3Phen doped PVK with different doping concentrations. The results indicate that there exists Frster energy transfer from PVK to Eu(UVA)3phen in the mixed system. It can get good color purity by optimizing the doping concentration of host and guest materials. And the authors can obtain the best doping concentration to be 4% in EL device.
