Summary: This study presents a facile approach for the one-step synthesis of yellow-green solid-state fluorescent carbon dots (CDs) without using a matrix. The synthesized CDs exhibit independent excitation and emission in various organic solvents. By drying the colloidal solution, high photoluminescence quantum yield yellow-green solid-state fluorescent CD powders can be obtained. These powders are then used to prepare high-performance white light-emitting diodes with excellent optical characteristics.

Summary: A novel photo-controlled solid-state fluorescence switching based on carbon dots (CDs) and diarylethene was designed and constructed. The fluorescence switching not only had excellent modulation efficiency, but also exhibited good photochromic properties. The mechanism of the reversible fluorescence modulation was attributed to the FRET between the CDs (energy donor) and the closed-ring diarylethene (energy acceptor). This work suggests the strategy of constructing solid-state fluorescence switching is feasible, and will provide new ways for the potential application of CDs and diarylethene.

Summary: Red-emitting carbon dots were designed as a fluorescent probe for the determination of MITX in human serum based on IFE. The R-CDs showed a decrease in fluorescence intensity and a red-shift in emission peak position with increasing MITX concentration. The developed detection probe exhibited a wide linear detection range of 0.096-30 μM and a low LOD of 0.032 μM for MITX. It was successfully applied to the determination of MITX in human serum samples, demonstrating good operability, low cost, and high accuracy.

Summary: Counterfeiting not only causes trillion-dollar economic losses annually, but also threatens human health, social equity, and national security. Researchers have developed a nanoprinting-assisted flash synthesis approach to create fluorescent nanofilms with physical unclonable function micropatterns in milliseconds. These unclonable patterns can be quickly and independently read out by fluorescence and topography scanning, greatly enhancing their security.

Summary: Carbon dots are a new class of nontoxic nanoemitters with excitation wavelength-dependent photoluminescence and high quantum yield. While most studies focus on blue/green emissions, longer wavelength emissions have important applications as well. Effective strategies for shifting the emission towards the red end of the spectrum are outlined, along with emphasis on key applications.

Summary: Passive daytime radiative cooling (PDRC) technology, while promising for global spacing cooling, faces limitations in practical application due to reduced cooling effectiveness caused by wear and dirt contamination. Researchers have developed a renewable armor structure using fluorinated hollow glass microspheres to enhance the anti-fouling and cooling properties of PDRC coatings. The coatings exhibit high solar reflectance and thermal emittance, leading to significant temperature reduction below ambient temperature.

Summary: The power conversion efficiency (PCE) of organic solar cells (OSCs) has reached 20% in recent years, thanks to the advantages of organic photoactive materials. Benzothiadiazole (BT) has attracted significant research attention as a building block of OSCs.

This review analyzes the progress made in the last decades, focusing on effective BT small-molecules and BT polymers for OSCs. The structure-property relationships, donor-acceptor matching criteria, and morphology control approaches are discussed. The remaining challenges and a personal perspective on the future advancement of OSCs are summarized.

Summary: Methane chemistry is a significant area of research in catalysis. Converting methane into value-added chemicals is desirable but challenging due to its high C-H bonding energy and lack of pi bonding or unpaired electrons. Photocatalytic partial oxidation of methane to liquid oxygenates is a promising technology for achieving high efficiency and selectivity under mild conditions. The choice and activation of oxidants are crucial for its performance.
