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.
