Abstract：Room-temperature phosphorescence（RTP）materials have garnered significant attention due to their prolonged luminescent lifetime，rendering themparticularlysuitable fornon-instantaneous excitationapplications. Carbon dots （CDs），as an emerging classof RTP materials，have sparked widespread interest among researchers owing totheirfacile preparation，lowtoxicity，cost-effectiveness，excellentopticalstability，andtunableopticalproperties.In this review，wecomprehensively summarizethe pivotal advancements achieved in RTPCDs materials.Initially，we delveinto the luminescence mechanismof RTP，elucidating theenergylevel structureunderlying phosphorescence emision.Subsequently，we elaborate on the synthetic strategies and modulation methods for both solidphase and water-solubleRTPCDs.Following this，we highlight their potential applications in information encryption，sensing，lightingand display，as well as biomedicine.Lastly，we discuss the primary challnges currently faced by water-soluble RTP CDs and offer insights into future development opportunities.
