Organic light emitting diodes (OLEDs) are highly promising as energy-efficient lighting and in flat panel displays. Much work is being done around the world and a recently accepted article in RSC Advances, by Yuezhong Meng, Shuanjin Wang and colleagues in China, reports on the preparation of a yellow-emitting iridium complex [Ir(DMP)3] for use in OLEDs.
An OLED doped with 2 wt% of the complex produced yellow emission at 576 nm with a maximum quantum efficiency of 8.7% at 5.93 mA/cm2, and CIE coordinates of (0.49, 0.50). Yellow OLEDs are of key importance for the production of white OLEDs (or WOLEDs) for solid-state lighting applications. Details of the synthesis, characterisation, OLED fabrication and performance are given.
