Carbon dots (CDs) are nanostructures containing mainly carbon atoms and abundant functional groups. With remarkable adjustable physicochemical properties, CDs have excellent hydrophilicity, photoluminescence (PL), biocompatibility, low toxicity. Although the numerous advantages make a research target for synthesizing advanced materials, some limitations pertinent must be corrected. Rare earth elements (RE) candidates doping CDs, obtaining hybrid materials called RE-CDs to optimize luminescence applicability, quantum yields. Hybrids allow combination of advantageous characteristics both RE, drastically improving their luminous magneto-optical imaging performance opening door practical technological applications. To date, no studies in literature provided in-depth analyses methods used prepare RE-CDs, characterization techniques used, challenges, critical analysis what could improved synthesis by proposing solutions. fill this gap, review initially presents detailed survey RE separately. Subsequently, addressed, as well obtainment, commonly characterizations, recent applications, from analyte detection functionality medical nanodevices. Finally, criticisms suggestions future work also discussed inspire new discoveries about potential derived RE-CDs.
