Abstract

High-efficiency deep blue organic light-emitting devices have been fabricated using asymmetrically substituted 9- (α -naphthyl)-10- (Β -naphthyl)-anthracene as blue host material and diphenyl-[4-(2- [1, 1′; 4′, 1″] terphenyl -4-yl-vinyl)-phenyl]amine as dopant emitter. With an optimized device structure and doping concentration, the deep blue electroluminescent (EL) device achieved an EL efficiency of 4.9 cdA and an external quantum efficiency of 4.4% at a current density of 20 mA cm2 at saturated blue Commission Internationale de l'Eclairage coordinates of (0.15, 0.13). The deep blue device also has a current efficiency which is invariable with driving conditions ranging from 10 to 100 mA cm2.
