Carbon dots (CDs) have excellent luminescence characteristics, such as good light stability, high quantum yield (QY), long phosphorescence lifetime, and a wide emission wavelength range, resulting in CDs' great success in optical applications. Understanding the structure-property relationships in CDs is essential for their use in optoelectronic applications. However, because of the complex nature of CD structures and synthesis processes, understanding the luminescence mechanism and structure-property relationships of CDs is a big challenge. This Perspective reviews the theoretical efforts toward the understanding of structure-property relationships and discusses the challenges that need to be overcome in future development of CDs.
碳点 (CDs) 具有优异的发光特性，例如良好的光稳定性、高量子产率 (QY)、长磷光寿命和宽发射波长范围，这使得 CDs 在光学应用中取得了巨大成功。了解 CDs 中的结构-性能关系对于它们在光电应用中的使用至关重要。然而，由于 CDs 结构和合成过程的复杂性，理解 CDs 的发光机制和结构-性能关系是一个巨大的挑战。本观点综述了在理解结构-性能关系方面的理论努力，并讨论了未来 CDs 发展中需要克服的挑战。
