摘　　要：对荧光碳点(carbon dots, CDs)基电致发光二极管(light-emitting diodes, LEDs)的最新研究进展进行综述。首先,介绍了CDs基电致LEDs的工作原理和CDs的合成方法;其次,综述了纯CDs作为发光层、掺杂CDs作为发光层和CDs作为界面传输层在电致LEDs的研究进展,重点总结了影响CDs基电致LEDs性能的主要因素,包括CDs的结构、CDs作为发光层的成膜性、CDs的发光性质以及器件结构;最后,给出目前CDs基电致LEDs面临的问题,并对其未来发展方向进行展望。This review summarizes the research progress in carbon dots(CDs)-based electroluminescent light-emitting diodes(LEDs). First, the synthesis method of CDs and the working principle of CDs-based electroluminescent LEDs are introduced. Second, electroluminescent LEDs with pure CDs and doped CDs in host as emission layer, and pure CDs as charge transport layer are disscused in detail, and the key factors affecting the performance of CDs-based electroluminescent LEDs are mainly analyzed, including the structure of CDs, the film-forming quanlity of CDs as emission layer, the luminescent properties of CDs, and the device structure. Finally, we also give the current problems and prospect for the future development of CDs-based electroluminescent LEDs.
