Korean J. Met. Mater. 2021;59(10):718-723.   Published online 2021 Sep 6
DOI: https://doi.org/10.3365/KJMM.2021.59.10.718

Abstract
We report a highly efficient quantum dot light emitting diode (QLEDs) with a radio frequency (RF) sputtered ZnO thin film as an electron transport layer (ETL) instead of the conventional ZnO nanoparticles (NPs) by solution process. ZnO NPs have been used as a key material to improve the performance of..... More

                        
A Study on the Stability of TiO2 Nanoparticles as an Electron Transport Layer in Quantum Dot Light-Emitting Diodes

Korean J. Met. Mater. 2021;59(7):476-480.   Published online 2021 Jun 16
DOI: https://doi.org/10.3365/KJMM.2021.59.7.476

Abstract
We report highly efficient and robust quantum dot light-emitting diodes (QLEDs) with Li-doped TiO2 nanoparticles (NPs) as an electron transport layer (ETL). As core materials, ZnO-based inorganic NPs can enhance the performance of QLEDs due to their suitable energy level and solution processability. However, their fast electron mobility and instability..... More
