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. Achieving controllable with predefined via adoption specific functionalization strategies prized goal current researchers field.In Account, we describe efforts made by our group synthesis, mechanism analysis, regulation, functional applications CPDs, particular emphasis on design core-shell tailored for fields optoelectronics energy. Specifically, through rational selection precursors, optimization reaction conditions, postmodification have demonstrated it possible regulate both core layers, thereby achieving full-spectrum emission, yield, persistent luminescence, thermally activated delayed fluorescence, laser action CPDs. Furthermore, established structure-performance proposed universal strategy synergistic interactions carbon-based surface micronanostructures. addition, unveiled luminescence cross-linked specifically "cross-linking synergistically inducing quantum-state luminescence", which addresses challenge efficient circularly polarized liquid solid phases Subsequently, strong cross-linking, dual-rigidity, ordering preparation methods were introduced, pioneering emission from blue near-infrared wavelengths. Additionally, developed new "confined composite nanocrystals CPDs", leading various high-performance hydrogen evolution catalysts water electrolysis.

The effective control over the self-assembly process of carbon dots (CDs) and their cluster luminescence in aggregated state is paramount significance challenge. This study, for first time, systematically explores photoluminescent behavior CDs state, which less understood compared to discrete state. By investigating effects concentration solvent environment, it's demonstrated that could exhibit dual emission properties, shifting from blue particle emissions red as they aggregate. key this tunable lies hydrogen bonding, drives modulates photo physical properties. These findings reveal through precise aggregation, can be engineered advanced optoelectronic applications, including light-emitting diodes (LEDs), secure information encryption, fingerprint authentication. report not only deepens understanding underlying mechanisms governing CDs' but also introduces a novel approach exploiting unique properties technological innovation.

Multimode luminescent materials exhibit tunable photon emissions under different excitation or stimuli channels, endowing them high encoding capacity and confidentiality for anti-counterfeiting encryption. Achieving multimode luminescence into a stable single material presents promising but remains challenge. Here, the downshifting/upconversion emissions, color-tuning persistent (PersL), temperature-dependent multi-color hydrochromism are integrated Er3+ ions doped Cs2NaYbCl6 nanocrystals (NCs) by leveraging shallow defect levels directed energy migration. The resulting NCs display strong static dynamic colorful in response to ultraviolet, 980-nm laser, X-ray. Additionally, distinct colors as temperature increases from 330 430 K. Surprisingly, it also demonstrates ability of reversible emission modal color water. Theoretical calculations experimental characterizations reveal that self-trapped exciton state (STEs), chlorine vacancy defects, ladderlike 4f contribute multimodal luminescence. More importantly, has extremely remarkable environmental stability, which can be stored air more than 18 months, showing commercial prospects. This work not only gives new insights lanthanide-based metal halide provides route developing nanomaterials

Abstract Thermally activated delay fluorescence (TADF) has great potential for information encryption, temperature detection, and bioimaging due to its long‐lived luminescence, temperature‐sensitive high signal‐to‐noise ratio. However, it is still a challenge establish TADF in aqueous environments. In this study, the composite with (M‐FNCDs) prepared using fluorine‐nitrogen co‐doped carbon dots (FNCDs) melamine. It worth mentioning that M‐FNCDs show stable under long‐wavelength excitation (470 nm) Moreover, distinctive temperature‐responsive properties exhibit good linear relationships range of 77–370 K. Simultaneously, suspension as ink utilized realize encryption/decryption their afterglow cannot be quenched an solution. More importantly, biocompatibility can target mitochondria lysosomes living cells, first time achieve ratio low background signal imaging organelles. This work proposes new strategy prepare solutions extend material applications future.
