Deep-red organic light-emitting diodes with stable

IntroductionResults and DiscussionAcknowledgementsIncreasing interest have been paid to deep-red and near-infrared OLEDs because of their potential application in fields like phototherapy,10 telecommunication11 and defense.12 However, the external quantum efficiency (EQE) of deep-red OLEDs with Commission Internationale de l'Eclairage (CIE) coordinate CIE x ≥ 0.70 is still low. What is more, the CIE coordinate under high current density is rarely discussed in previous reports. Under high current density, the shift of recombination zone could lead to blue shift, giving rise to emission with lower CIE x value.13 The key issues to obtain an ideal deep-red devices with CIE x ≥ 0.7 are the emission peak wavelength and the bandwidth of spectrum.14To get emission with a stable CIE coordinate, device needs to have balanced hole and electron injection, and stable recombination zone without significant shift at high current density. To meet these requirements, both material and device configuration should be carefully optimized. Fujii et al....Get price
