Abstract

Highly luminescent carbon dots (CDs) have garnered significant attention and are increasingly utilized in various fields. Despite its importance, there has been a lack of comprehensive reviews focusing specifically on highly luminescent CDs. It is aimed here to fill that gap by exploring CDs with high photoluminescence quantum yield (PLQY), starting with an examination of the luminescent mechanisms underlying highly luminescent CDs. The selection of synthetic raw materials and preparation methods along with the research progress are reviewed and the information on highly luminescent CDs across various luminescent bands is then statistically summarized in several tables. Subsequently, the structural features, synthesis methods, and purification strategies that lead to high PLQY in CDs are summarized based on analyzing collected examples of highly luminescent CDs. Furthermore, the highly luminescent‐based multifunctional applications of CDs in bioimaging, light‐emitting diodes, luminescent solar concentrators, and lasers are introduced. Finally, the current research landscape is evaluated, existing challenges are identified, and feasible directions are proposed for future development.

高发光碳点的研究进展

高发光碳点（CDs）已引起人们的广泛关注，并在各个领域得到越来越多的应用。尽管它很重要，但一直缺乏专门针对高发光cd的全面评论。本文的目的是通过探索具有高光致发光量子产率（PLQY）的cd来填补这一空白，首先研究高发光cd的发光机制。综述了高发光CDs合成原料的选择、制备方法及研究进展，并对不同发光波段高发光CDs的研究进展进行了统计总结。随后，在分析高发光CDs样品的基础上，总结了导致CDs高PLQY的结构特征、合成方法和纯化策略。此外，还介绍了CDs在生物成像、发光二极管、发光太阳能聚光器和激光器等领域的高度发光多功能应用。最后，对目前的研究现状进行了评价，指出了存在的挑战，并提出了未来发展的可行方向。
