Effect of the greenish-yellow emission on the color rendering index (CRI) of white organic light-emitting devices (WOLEDs) was demonstrated. The correlated color temperature and CRI of the three-component WOLEDs were numerically modeled. The simulation predicted that the greenish-yellow emission is beneficial to improve the CRI of three-component WOLED. The corresponding hybrid WOLED with greenish-yellow dopant was carefully designed and fabricated. In a tolerable deviation from the Planckian locus, such WOLED shows general CRI values above 85 and a power efficiency of 10.4 lm/W. (C) 2014 Elsevier B.V. All rights reserved.
