Abstract The development of single‐system materials that exhibit both multicolor room‐temperature phosphorescence (RTP) and thermally activated delayed fluorescence (TADF) with tunable after glow colors channels is challenging. In this study, four metal‐free carbon dots (CDs) are developed through structural tailoring, panchromatic high‐brightness RTP achieved via strong chemical encapsulation in urea. maximum lifetime quantum yield reaches 2141 ms 56.55%, respectively. Moreover, CDs‐IV@urea, prepared coreshell interaction engineering, exhibits a dual afterglow red green TADF. degree conjugation functional groups precursors affects the binding interactions nitrogen cladding on CDs, which turn stabilizes triplet energy levels gap between S 1 T (Δ E ST ) to induce RTP. enhanced wrapping lowers Δ , promoting reverse intersystem crossing, leads This fully state, thus stabilizing material water, even extreme environments such as acids oxidants. These tested multicolor, time, temperature multiencryption well vivo bioimaging. Hence, these have promising practical applications information security biomedical diagnosis treatment.

Abstract Comprehensive research into afterglow emission in the near‐infrared (NIR) region of carbon dots (CDs) is currently lacking. In this study, highly efficient multicolor CDs are synthesized with fluorescence from blue to NIR using Rhodamine 6G. Boron oxide (B 2 O 3 ) employed as a matrix for encapsulating and confining CDs, inhibiting triplet exciton quenching. Furthermore, structural rigidity enhanced due formation carbon‐boron (C─B) covalent bonds between B , achieving tunable ranging 463 722 nm lifetimes up 801 ms. The green–yellow composite exhibits an impressive quantum yield 37.67% while demonstrating thermally activated delayed (TADF). Thus, coated onto alternating‐current light‐emitting diode (BAC‐LED) fabricate white AC‐LED, which successfully prepared Commission Internationale de L'Eclairage (CIE) at coordinates (0.32, 0.34), accompanied by color rendering index (CRI) reaching 81.1. bright compensates zero‐point flickering BAC‐LED, resulting stable gentle emission. potential applications these luminescent materials optoelectronic devices undoubtedly widened remarkable advancement.

ConspectusCarbon dots (CDs), as a novel type of fluorescent nanocarbon material, attract widespread attention in nanomedicine, optoelectronic devices, and energy conversion/storage due to their excellent optical properties, low toxicity, high stability. They can be classified graphene quantum dots, carbon carbonized polymer (CPDs). Among these, CPDs exhibit tunable structures components that allow fine-tuning making them one the most popular types CDs recent years. However, structural complexity stimulates deep exploration relationship between unique structure luminescent performance. As an organic-inorganic hybrid system, diversity self-limited state cores polymer-hybrid shell layers makes understanding underlying mechanisms structure-property relationships very challenging task. In this context, elucidating composition factors affect properties is vital if enormous potential realized.
