Carbon dot (CD) based long‐lived afterglow emission materials have attracted attention in recent years, but demonstration of white‐light room‐temperature afterglow remains challenging, due to the difficulty of simultaneous generation of multiple long‐lived excited states with distinct chromatic emission. In this work, a white‐light room‐temperature long‐lived afterglow emission from a CD powder with...
Sonodynamic therapy as a promising noninvasive modality is being developed for tumor therapy, but there is a lack of next‐generation sonosensitizers that can generate full ROS at high yields and simultaneously deplete elevated levels of glutathione (GSH) in tumor cells. Semiconductor p‐n junctions are engineered as high‐efficacy sonosensitizers for sonodynamic tumor eradication using pyridine N‐doped...
Conventional synthesis of carbon dots (CDs) mostly involves a hydrothermal or solvent‐thermal reaction which needs relatively high temperature and pressure. In this work, ionic liquid is used to assist in fast synthesizing CDs with an ultrahigh photoluminescent quantum yield (98.5%) by heating at a low temperature (≤100 °C) and at atmospheric pressure. In addition, through this approach, tunable multicolor...
Pollution‐induced degradation of the environment is a serious problem for both developing and developed countries. Existing remediation methods are restricted, necessitating the development of novel remediation technologies. Nanomaterials with unique characteristics have recently been developed for remediation. Quantum dots (QDs) are semiconductor nanoparticles (1–10 nm) with optical and electrical...
Exploring appropriate precursors has been proposed to be a promising strategy for the creation of artificial enzymes that are emerging as alternatives of natural enzymes. Herein, inspired by the catalytic activities of ribose nucleic acid, using ribonucleosides as precursors including adenosine, guanosine, cytidine, and uridine, respectively, four carbonic aggregates, namely, carbon dots (A‐CDs, G‐CDs,...
Ultrasmall nanoparticles are often grouped under the broad umbrella term of “nanoparticles” when reported in the literature. However, for biomedical applications, their small sizes give them intimate interactions with biological species and endow them with unique functional physiochemical properties. Carbon quantum dots (CQDs) are an emerging class of ultrasmall nanoparticles which have demonstrated...
Long‐lived room temperature phosphorescence (RTP) materials are widely utilized in the field of biological and chemical sensing, due to their unique characteristics of long‐lived luminescence and no background autofluorescence. However, the realization of full‐color RTP in aqueous solution still remains a great challenge. Herein, a feasible strategy for achieving high stability and full‐color RTP...
The energy density of lithium‐sulfur batteries (LSBs) is currently hampered by modest sulfur loadings and high electrolyte/sulfur ratios (E/S). These limitations can potentially be overcome using easy‐to‐infiltrate sulfur hosts with high catalytic materials. However, catalytic materials in such hosts are very susceptible to agglomeration due to the lack of efficient confinement in easy‐to‐infiltrate...
The continuous white‐light emission of carbon dots (CDs) can be applied to producing multicolor laser emissions by one single medium. Meanwhile, the solid‐state emission greatly contributes to its practical application. In this work, a strategy to realize the in‐situ hybridization of silane‐functionalized CDs (SiCDs) and 1,3,5‐benzenetricarboxylic acid trimethyl ester (Et3BTC) by a one‐pot solvothermal...
Multicolor Lasers
In article number 2203152, Wenfei Zhang, Hailong Zhang, Zheng Xie, and co‐workers report a strategy to realize the in‐situ hybridization of carbon nanodots and 1,3,5‐benzenetricarboxylic acid trimethyl ester crystals. The hybrid crystals exhibit ultra‐broadband multicolor random laser over the near ultraviolet‐visible region and continuous white‐light fluorescence. The structure...
Synthesis of high‐efficiency, cost‐effective, and stable photocatalysts has long been a priority for sustainable photocatalytic CO2 reduction reactions (CRR), given its importance in achieving carbon neutrality goals under the new development philosophy. Fundamentally, the sluggish interface charge transportation and poor selectivity of products remain a challenge in the CRR progress. Herein, this...
