27.3: Efficient Red Organic Electroluminescent Devices Based on a Novel co‐Host Emitter System

We have developed an efficient red OLED device based on the fluorescent dye DCJTB doped in a novel co-host matrix system of 9,10-di(2-naphthyl) anthracene (ADN) and Alq3, which achieved a luminance efficiency of 4.2– 5.5 cd/A at 20 mA/cm2 with a CIEx, y color coordinate of [0.64, 0.35] – [0.62, 0.37]. At high ADN concentration (>60%), this co-hosted emitter system has the advantage of alleviating the current-induced fluorescence quenching problem often encountered in red organic EL devices and greatly improves the EL efficiency over a wide range of drive current conditions.
