Abstract The fluorescence discoloration of carbon dots (CDs) induced by UV irradiation without chemical modification has proved to be difficult achieve. Herein, the synthesis UV‐sensitive CDs with photo‐induced is reported using a heteroatom co‐doped hydrothermal method and red‐emitting (R‐CDs) can tuned under from red yellow green, showing new strategy for simpler easier modulating luminescence CDs. UV‐induced color change involves changes molecular fluorophores oxygen defects on surface irradiation. Results show that results in transformation part internal groups, such as C─O CO. Based unique color‐changing property R‐CDs, UV‐sensing film fabricated, which expected further applied field detection. Furthermore, combining fluorescent ink binary code Morse code, it encrypt decrypt information specific text. This concept provides strong technical support next generation advanced encryption.

Abstract Highly luminescent carbon dots (CDs) have garnered significant attention and are increasingly utilized in various fields. Despite its importance, there has been a lack of comprehensive reviews focusing specifically on highly CDs. It is aimed here to fill that gap by exploring CDs with high photoluminescence quantum yield (PLQY), starting an examination the mechanisms underlying The selection synthetic raw materials preparation methods along research progress reviewed information across bands then statistically summarized several tables. Subsequently, structural features, synthesis methods, purification strategies lead PLQY based analyzing collected examples Furthermore, luminescent‐based multifunctional applications bioimaging, light‐emitting diodes, solar concentrators, lasers introduced. Finally, current landscape evaluated, existing challenges identified, feasible directions proposed for future development.
