摘要

量子点（QDs）因其易于溶液处理和高色纯度而在发光二极管（LEDs）中的应用正受到广泛关注。此外，目前的量子点发光二极管（QLED）具有与有机发光二极管相当的高电致发光性能和使用寿命。然而，用于下一代显示器的 QLED 在商业化方面仍面临一些挑战。其中一个关键问题是，与红色和绿色 QLED 相比，蓝色 QLED 的效率和寿命较低，这归因于深价带和宽带隙。在本研究中，我们讨论了旨在提高蓝色 QLED 效率的最新进展，并探讨了其商业化必须应对的挑战。

Recent Progress on Blue Quantum Dot Light-Emitting Diodes from Materials to Device Engineering

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.
