Abstract
Quantum dots (QDs) are gaining widespread attention for their applications as light-emitting diodes (LEDs) owing to their ease of solution processing and high color purity. Furthermore, current QD light-emitting diodes (QLEDs) exhibit high electroluminescence performance and lifetime comparable to those of organic LEDs. However, some challenges remain in the commercialization of QLEDs for next-generation displays. One key issue is that blue QLEDs exhibit lower efficiency and lifetimes compared to red and green QLEDs, which is attributed to a deep valence band and wide bandgap. In this study, we discuss recent developments that aim to enhance the efficiency of blue QLEDs and explore the challenges that must be addressed for their commercialization.
期刊介绍：
The Korean Journal of Chemical Engineering provides a global forum for the dissemination of research in chemical engineering. The Journal publishes significant research results obtained in the Asia-Pacific region, and simultaneously introduces recent technical progress made in other areas of the world to this region. Submitted research papers must be of potential industrial significance and specifically concerned with chemical engineering. The editors will give preference to papers having a clearly stated practical scope and applicability in the areas of chemical engineering, and to those where new theoretical concepts are supported by new experimental details. The Journal also regularly publishes featured reviews on emerging and industrially important subjects of chemical engineering as well as selected papers presented at international conferences on the subjects.
