Abstract: ： Room-temperature phosphorescence (RTP) materials have garnered significant attention due to their prolonged luminescent lifetime， rendering them particularly suitable for non-instantaneous excitation applications.Carbon dots (CDs)， as an emerging class of RTP materials， have sparked widespread interest among researchers ow • ing to their facile preparation， low toxicity， cost-effectiveness， excellent optical stability， and tunable optical proper• ties.In this review， we comprehensively summarize the pivotal advancements achieved in RTP CDs materials.Ini• tially， we delve into the luminescence mechanism of RTP， elucidating the energy level structure underlying phospho• rescence emission.Subsequently， we elaborate on the synthetic strategies and modulation methods for both solidphase and water-soluble RTP CDs.Following this， we highlight their potential applications in information encryp• tion， sensing， lighting and display， as well as biomedicine.Lastly， we discuss the primary challenges currently faced by water-soluble RTP CDs and offer insights into future development opportunities.
