Abstract

The authors demonstrate a fluorescent white organic light-emitting device (WOLED) with double emissive layers. The yellow and blue dyes, 5,6,11,12-tetraphenylnaphthacene and N-(4-((E)-2-(6-((E)-4-(diphenylamino)styryl)naphthalen-2-yl)vinyl)phenyl)-N-phenylbenzenamine, are doping into the same conductive host material, N,N′-dicarbazolyl-4-4′-biphenyl). The maximum luminance and power efficiency of the WOLED are 14.6 cd/A and 9.5 lm/W at 0.01 mA/cm2, with the maximum brightness of 20 100 cd/m2 at 17.8 V. The Commission International de L’Éclairage coordinates change slightly from (0.27, 0.37) to (0.28, 0.36), as the applied voltage increases from 6 V to 16 V. The high efficiencies can be attributed to the balance between holes and electrons.
