  • Iridium complex and electroluminescent device using the same
    Publication number: 20060263630
    Abstract: An iridium complex is used as a phosphorescent material in an organic electroluminescence (OEL). Use this complex as the red light guest dopant emitter of the phosphorescent material, then apply the phosphorescent material to the OEL light-emitting layer, a red light that is very close to pure red can be achieved. In addition, the iridium complex can increase the thermal stability of the OEL, due to their high conjugated structure.
