摘要

The authors have demonstrated hybrid white organic light-emitting diodes (WOLEDs) using 1,4-bis[2-(7-N-diphenyamino-2-(9,9-diethyl-9H-fluoren-2-yl))vinyl] benzene as a fluorescent blue emitter and iridium(III) bis(2-phenylquinoline) acetylacetonate as a phosphorescent red emitter. As the spacer ratio of 4,4',4"-tris-(N-carbazolyl) triphenylamine to 4,7-diphenyl-1,10-phenanthroline changed from 1 :1 to 1:3, WOLEDs showed changes from cold to warm electroluminescent characteristics. The optimized WOLEDs of 1 : 3 spacer ratio showed an external quantum efficiency of 7.40%, a luminous efficiency of 14.79cd/A, and Commission Internationale de l'Eclairage coordinates of (0.43,0.39) at 1000cd/m~2.
