Summary: The study revealed structural modifications and changes in ultrafast relaxation dynamics of red-emitting C-dots due to boron doping. Boron doping increased the percentage of pyrridinic nitrogen and formed an additional excited state level, slowing down the initial relaxation process and prolonging the overall lifetime of the C-dots.

Summary: In this study, the photophysical characteristics of core/shell InP/ZnS quantum dots (InP-QDs) were analyzed in cell culture medium, salt solutions, and directly in the cells. It was found that InP-QDs were internalized into endolysosomes in HeLa and A549 cells with similar dynamics to Cd-based QDs, but the two cell lines accumulated them differently. InP-QDs were reliably detected in the endosomes despite their low quantum yields. Factors such as cell culture medium, acidic pH, and salt solutions were found to affect the photoluminescence lifetime of InP-QDs. The scatter between endosomes in the same cell was observed, indicating the complex impact of these factors on the state of InP-QDs. The toxicity of InP-QDs for both cell lines at concentrations higher than 20 nM was demonstrated.

Summary: Nitrogen-doped graphene quantum dots (N-GQDs) with prime fluorescence properties were synthesized through a simple one-pot hydrothermal method by using citric acid as carbon source and ammonia (A-GQDs) or urea (UGQDs) as nitrogen source. The differences in particle size and nitrogen-containing doped rings between A-GQDs and U-GQDs lead to the differences in optical properties. Optimizing reaction conditions can result in U-GQDs with high quantum yield (QY) of 54%.

Summary: To address the instability of colloidal cesium lead halide perovskite nanocrystals (CsPbX3 PNCs), a stapled ligand called perfluoroglutaric acid (PFGA) is proposed to effectively passivate the surface of CsPbBr3 PNCs. The PFGA-capped CsPbBr3 PNCs exhibit high photoluminescence quantum yield, outstanding dispersion in polar solvents, and excellent stability after rigorous washing and long-term storage. These findings provide insight into surface engineering strategies for producing highly emissive and stable PNCs and broadening their sensing applications in polar media.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
