| 摘要: 与传统室温磷光(RTP)材料相比，室温磷光碳点(RTP-CDs)具有生物相容性好、毒性较低和性能稳定等优点，近些年获得了研究者们的青睐。然而，其磷光寿命较短，通常为毫秒级水平，这也限制了其应用。因此，如何促进碳点的系间穿越与稳定碳点的激发三线态是实现其超长室温磷光(URTP)发射与应用的关键。本文依据近年来超长室温磷光碳点(URTP-CDs)的最新研究进展，归纳总结了其构建策略，及其在防伪与信息加密、传感、生物成像和发光二极管等方面的应用，并对其发展前景进行了展望。 | |

| Abstract: Compared with traditional room temperature phosphorescent (RTP) materials, room temperature phosphorescent carbon dots (RTP-CDs) have the advantages of good biocompatibility, low toxicity, and stable performance, and have been favored by researchers in recent years. However, its phosphorescent lifetime is usually short, in the millisecond range, limiting its application. Therefore, promoting the intersystem crossing of carbon dots and stabilizing the excited triplet state of carbon dots is the key to realizing the emission and application of ultralong room temperature phosphorescent (URTP). Based on the latest research progress of ultralong room temperature phosphorescent carbon dots (URTP-CDs) in recent years, this paper summarizes its construction strategies and its applications in anti-counterfeiting and information encryption, sensing, biological imaging, and light-emitting diode, and looks forward to its development prospects. | |
