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

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 TiO<sub>2</sub> Nanoparticles as an Electron Transport Layer in Quantum Dot Light-Emitting Diodes
TiO2 나노입자를 전자 수송층으로 사용한 양자점 발광다이오드의 용액 안정성 연구

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

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

Transforming Carbon Black into Graphene Oxide Quantum Dots by Pulsed Laser Ablation in Ethanol
Jung-Il Lee, Jeong Ho Ryu
Korean J. Met. Mater. 2020;58(11):808-814.   Published online 2020 Oct 21
DOI: https://doi.org/10.3365/KJMM.2020.58.11.808

Graphene oxide quantum dots (GOQDs) are nanometer-sized graphene oxide fragments that exhibit unique properties, making them interesting candidates for a range of new applications. Carbon black, one of the commercially available carbon precursors, is produced by the thermal decomposition or incomplete combustion of organic compounds. It is commonly used as..... More

Synthesis and Characterization of ZnO/TiO<sub>2</sub> Photocatalyst Decorated with PbS QDs for the Degradation of Aniline Blue Solution
Jong-Ho Lee, Hong-Joo Ahn, Jeong-Il Youn, Young-Jig Kim, Su-Jeong Suh, Han-Jun Oh
Korean J. Met. Mater. 2018;56(12):900-909.   Published online 2018 Dec 5
DOI: https://doi.org/10.3365/KJMM.2018.56.12.900

A ZnO/TiO2 photocatalyst decorated with PbS quantum dots (QDs) was synthesized to achieve high photocatalytic efficiency for the decomposition of dye in aqueous media. A TiO2 porous layer, as a precursor photocatalyst, was fabricated using micro-arc oxidation, and exhibited irregular porous cells with anatase and rutile crystalline structures. Then, a..... More
