[OLEDp2-4] High Efficiency Green Quantum Dot Light-Emitting Diodes with Surface-treated Indium Phosphide

*Wei Jiang1, Hee Yeop Chae1 (1. SungKyunKwan University (Korea))

Keywords:Indium phosphide quantum dots, surface treatment, green quantum dot light emitting diodes

The multi-shelled green InP QDs were synthesized by using the phosphorus source of (DMA)3P and the narrow FWHM of 46nm was obtained. The PLQY of 64% was achieved after the surface treatment and the maximum quantum efficiency of 2.68% and the current efficiency of 7.7cd/A were achieved for quantum dot light emitting diodes.
