Ultra Simple Fluorescent White Organic Light-Emitting Diodes Using Fluorescent Green-Yellow Emitter and Blue Host
2010
The authors have demonstrated ultra simple fluorescent white organic light-emitting diodes using fluorescent green-yellow emitter of 9,10-bis[4-(di-4-tert-butylphenylamino) styryl]anthracene and blue host of 2-methyl-9,10-di(2-naphthyl)anthracene. The optimized device at the extremely low doping concentration (0.2 wt.%) of green-yellow emitter showed a luminous efficiency of 7.18 cd/A, a power efficiency of 5.64 lm/W at 100 cd/m2, and a Commission Internationale de I'Eclairage coordinates of (0.35, 0.43) at 6 V, respectively.
