Due to the prominent characteristics of carbon-based luminescent nanostructures (known colloquially as carbon dots), such as inexpensive precursors, excellent hydrophilicity, low toxicity, and intrinsic fluorescence, these nanomaterials are regarded as potential candidates to replace traditional quantum dots in some applications. As such, research in the field of carbon dots has been increasing in recent years. In this mini-review, we summarize recent progress in studies of multicolor carbon dots focusing on potential photoluminescence (PL) mechanisms, strategies for effective syntheses, and applications in ion/molecule and temperature sensing, light emitting diodes and high-resolution bioimaging techniques.
由于碳基发光纳米结构（俗称碳点）具有显著的特点，如廉价的前体、优异的亲水性、低毒性和固有荧光性，这些纳米材料被认为是一些应用中替代传统量子点的潜在候选材料。因此，近年来碳点领域的研究一直在增加。在这篇小型综述中，我们总结了近年来关于多色碳点的研究进展，重点介绍了潜在的光致发光（PL）机制、有效合成策略以及在离子/分子和温度传感、发光二极管和高分辨率生物成像技术中的应用。
