Paper Abstract

We report efficient blue electroluminescence (EL) devices fabricated using 9,10-diphenylanthracene (DPA) as an active emitting material. Although DPA exhibits fluorescence in the blue spectral region with high quantum efficiency, its EL efficiency has been previously reported poor. By doping DPA into a bathocuproine (BCP) layer that acts as a hole-blocking layer, we can successfully fabricate very efficient blue EL devices with the Commission Internationale de L’Eclairage (CIE) chromaticity coordinates of (0.145, 0.195). The devices show a luminous efficiency of 2.9 cd/A at 200 cd/m2 and a maximum luminance of about 10344 cd/m2 at 16.6 V.
