- Light emission efficiency of red phosphorescent organic light-emitting diodes was improved by using a double doping structure in light emitting
layer. Red devices with tris(2-phenylpyridine) iridium (Ir(ppy)3) as a co-dopant for tris(1-phenylisoquinoline) iridium (Ir(piq)3) showed higher
efficiency than Ir(piq)3 device. Ir(ppy)3 acted as a sensitizer for energy transfer from (4,4 -N,N -dicarbazole)biphenyl to Ir(piq)3 and enhanced
luminance efficiency of Ir(piq)3 by 30%.
