High-Efficiency Polymer-Based Electrophosphorescent Devices, Xiong Gong

High efficiency electrophosphorescence has been achieved by using [Ir(DPF)3]-doped polyvinylcarbazole/biphenyl-1,3,4-oxadiazole co-polymers (see Figure). Light-emitting devices with luminous efficiencies up to 36 cd/A can be realized with polymeric host/heavy metal complex guest systems, fabricated by processing the luminescent layer from solution.
