High-Efficiency Blue and White Organic Light-Emitting Devices Incorporating a Blue Iridium Carbene Complex
A blue iridium carbene complex realizes high-efficiency blue and white OLEDs. For a blue OLED, eta(p,max) is recorded to be 35.9 lm W-1. For a white OLED, eta(p,max) and eta(p,1000) are measured to be 59.9 lm W-1 and 43.3 lm W-1, respectively, without any light-outcoupling enhancement. This white OLED also shows an illumination-acceptable color rendering index (CRI) over 80.
