The lifetime of red phosphorescent organic light-emitting diodes with a double doping structure was studied. Green and red phosphorescent dopants were co-doped in the emitting layer and the lifetime of the red devices with the doubly doped emitting structure was dependent on the doping concentration of the green dopant due to the energy transfer from the green dopant to the red dopant.

Keywords:Lifetime;Double doping;Red phosphorescent devices
