Carbon dots (CDs), a class of carbon-based nanomaterials with dimensions less than 10 nm, have attracted significant interest since their discovery. They possess numerous excellent properties, such as tunability of photoluminescence, environmental friendliness, low cost, and multifunctional applications. Recently, a large number of reviews have emerged that provide overviews of their synthesis, properties, applications, and their composite functionalization. The application of CDs in the field of optoelectronics has also seen unprecedented development due to their excellent optical properties, but reviews of them in this field are relatively rare. With the idea of deepening and broadening the understanding of the applications of CDs in the field of optoelectronics, this review for the first time provides a detailed summary of their applications in the field of luminescent solar concentrators (LSCs), light-emitting diodes (LEDs), solar cells, and photodetectors. In addition, the definition, categories, and synthesis methods of CDs are briefly introduced. It is hoped that this review can bring scholars more and deeper understanding in the field of optoelectronic applications of CDs to further promote the practical applications of CDs.
碳点（CDs）是一类尺寸小于10纳米的碳基纳米材料，自发现以来就引起了广泛关注。它们具有许多优异的性能，如光致发光的可调性、环境友好性、低成本以及多功能应用。最近，出现了大量综述，对其合成、性能、应用及其复合功能化进行了概述。由于其优异的光学性能，碳点在光电子领域的应用也取得了前所未有的发展，但该领域对它们的综述相对较少。为了深化和拓宽对碳点在光电子领域应用的理解，本综述首次详细总结了它们在发光太阳能聚光器（LSCs）、发光二极管（LEDs）、太阳能电池和光电探测器领域的应用。此外，还简要介绍了碳点的定义、类别和合成方法。希望本综述能为学者们在碳点光电子应用领域带来更多、更深入的理解，以进一步推动碳点的实际应用。
