Rare earth (RE) elements are widely used in the luminescence and magnetic fields by virtue of their abundant 4f electron configurations. However, the overall performance and aqueous stability of single-component RE materials need to be urgently improved to satisfy the requirements for multifunctional applications. Carbon nanodots (CNDs) are excellent nanocarriers with abundant functional surface groups, excellent hydrophilicity, unique photoluminescence (PL) and tunable features. Accordingly, RE–CND hybrids combine the merits of both RE and CNDs, which dramatically enhance their overall properties such as luminescent and magnetic-optical imaging performances, leading to highly promising practical applications in the future. Nevertheless, a comprehensive review focusing on the introduction and in-depth understanding of RE–CND hybrid materials has not been reported to date. This review endeavors to summarize the recent advances of RE–CNDs, including their interaction mechanisms, general synthetic strategies and applications in fluorescence, biosensing and multi-modal biomedical imaging. Finally, we present the current challenges and the possible application perspectives of newly developed RE–CND materials. We hope this review will inspire new design ideas and valuable references in this promising field in the future.

当稀土遇到碳纳米点时：机理，应用和前景

稀土（RE）元素因其丰富的4f电子构型而广泛用于发光和磁场中。但是，单组分稀土材料的整体性能和水稳定性需要紧急改善，以满足多功能应用的要求。碳纳米点（CND）是出色的纳米载体，具有丰富的功能性表面基团，出色的亲水性，独特的光致发光（PL）和可调特性。因此，RE-CND混合体结合了RE和CND的优点，极大地增强了它们的整体性能，例如发光和磁光成像性能，从而在未来具有广阔的应用前景。不过，迄今为止，尚未有针对RE-CND混合材料的介绍和深入理解的全面综述。本文旨在总结RE-CND的最新进展，包括其相互作用机制，一般合成策略及其在荧光，生物传感和多模式生物医学成像中的应用。最后，我们介绍了最新开发的RE-CND材料的当前挑战和可能的应用前景。我们希望这次审查能在未来这个有希望的领域中激发新的设计思想和有价值的参考。我们介绍了最新开发的RE-CND材料的当前挑战和可能的应用前景。我们希望这次审查能在未来这个有希望的领域中激发新的设计思想和有价值的参考。我们介绍了最新开发的RE-CND材料的当前挑战和可能的应用前景。我们希望这次审查能在未来这个有希望的领域中激发新的设计思想和有价值的参考。
