While device was statically stored 602 hrs, the external quantum efficiency (EQE) of QLED increased from 4.8% to 7.8%, which resulted from the enhancement in electron injection at quantum dot (QD)/ electron transporting layer (ETL) interface. It was confirmed by the measurement of the depth profile of X-ray photoelectron spectroscopy (XPS). It indicated that cathode material, aluminum (Al), diffused into ETL material, zinc oxide (ZnO), leading to aluminium zinc oxide (AZO) alloy, Al doped ZnO. ? 2021 SID. |
