[OLEDp2-2] The Effect of Particle Size on the Optical and Electrical Characteristics of Quantum Dot Light-Emitting Diode using Zinc Oxide Nanoparticles

*Da-Young Park1, Dae-gye Moon1 (1. Soonchunhyang University (Korea))

Keywords:Quantum Dot Light-Emitting Diode, Zinc Oxide Nanoparticles, Particle Size

The electrical and optical characteristics of QLEDs with 3 and 8 nm ZnO nanoparticles (NPs) were investigated. The QLED with 8 nm ZnO NPs exhibited maximum luminance of 64,360 cd/m2 and 4.5 times higher current efficiency compared to the 3 nm ZnO device.
