Abstract Rechargeable Zn‐based batteries provide a compelling supplement to subsistent energy storage devices owing their high density, good safety, and low cost. Nevertheless, inherent imperfections such as dendrite growth, side reactions, andante reaction kinetics, severely impede commercialization. As new 0D nanomaterials, carbon dots (CDs) with unique characteristics excellent electrochemical activity, exhibit promising potential exploitation in electrochemistry electrocatalysis areas. Herein, the adhibition of CDs resolving aforementioned drawbacks is introduced. To begin with, concepts, physicochemical properties, synthetic methods are discussed. Next, recent developments advances exploiting respectively ameliorating performance Zn anode, cathode, electrolytes ion bifunctional electrocatalytic activities including oxygen reduction evolution for Zn‐air batteries, roundly reviewed minutely generalized. Finally, current challenges prospects surveyed well, aiming offer reference blossom advanced batteries.

Abstract Luminescent solar concentrators (LSCs) can convert sunlight to clean energy by serving as large‐area collectors of sunlight. Benefiting from their large‐area, semi‐transparency, and lightweight characteristics, LSCs have gained a great attention. However, optical efficiency is limited the low quantum yield (QY) small Stokes shift conventional photoluminescent materials. Carbon dots (C‐dots) are promising alternatives, yet achieving both high QY large has proven challenging. Here, simple, controllable vacuum heating method introduced synthesize highly efficient C‐dots using citric acid‐urea‐cyanuric acid‐CaCl 2 system. The cyanuric acid‐capped exhibit outstanding properties, including 94.3% in solution 100% polymer matrix, 0.64 eV, exceptional photostability, making them ideal for LSC applications. Ultrafast transient absorption spectroscopy provides insights into exciton dynamics. An (25 cm ) based on these achieves an 13.82% ± 0.30%, while its attached photovoltaic cell attains power conversion 4.82% 0.10% under natural (80 mW −2 ), marking highest performance reported C‐dot‐based LSCs. These results highlight potential advanced solid‐state lighting technologies.

Abstract Room temperature phosphorescence (RTP) materials have broad applications in the field of optical devices due to tunable wavelengths and lifetimes. However, creating efficient RTP that possess multiple properties remains a challenge. Herein, novel approach is developed situ form carbon quantum dots (C‐dots) embedded boron nitride carbide oxide (B‐N‐C‐O) matrices by introducing nitrogen, phosphorus, dopants into C‐dots (P/B/N doped C‐dots), enabling dual emissions time‐dependent afterglow. P/B/N are synthesized vacuum‐assisted gradient heating using ethylenediamine, phosphoric acid, boric acid as precursors with yield 20 g per batch. The introduction provided triplet states, which enable and, long phosphorescent lifetime ranging from 0.98 1.30 s. formation surrounding enables ultrahigh up 50%, surpassing most recently reported C‐dots. To demonstrate potential C‐dots, they used anti‐counterfeiting ink dyes for security codes polyester yarn, showing their suitability high‐level applications. This work provides an effective route large‐scale synthesis highly preparation high‐performance devices.

Endogenous derivatives, inevitably introduced during carbonized polymer dots (CPDs) synthesis, are considered to significantly influence their sensing performance. In this study, comparative studies on CPDs prepared via hydrothermal methods (CPDs-H2O) and airflow-assisted melt polymerization (CPDs-AMP) reveal that CPDs-H2O, containing abundant exhibit superior stability robustness in Fe3+ both solution cells compared derivative-deficient CPDs-AMP. Mechanistic investigations highlight the crucial role of endogenous derivatives enhancing intrinsic frameworks, challenging conventional perceptions providing valuable insights for designing robust CPDs-based sensors practical applications.
