Extremely low voltage white organic light-emitting devices (WOLEDs) with fluorescent emitters are realized via the p-i-n structure. In this work, the influence of various electron blocking layer /hosts for fluorescent dye 5,6,11, 12-tetraphenylnaphthacene (rubrene) are discussed. White light is attributed to two complementary. Characteristics of WOLED reach 1000 cd/m2 at 2.9V, and 10000 cd/m2 at 4.7 V with the maximum power efficiency of 8.7 lm/W at 2.5V. The commission internationale de 1'Eclairage chromaticity coordinate changes from (0.36, 0.45) at 1000cd/m2 to (0.33, 0.42) at 10000cd/m2 showing high color stability.
Keywords:White light-emitting; Color-stability; Efficiency;low driving-voltage
