Abstract The process of N‐doping is frequently employed to enhance the properties carbon quantum dots. However, precise requirements for nitrogen precursors in producing high‐quality N‐doped dots (NCQDs) remain undefined. This research systematically examines influence various dopants on morphology, optical features, and band structure NCQDs. are synthesized using an efficient, eco‐ friendly, rapid continuous hydrothermal flow technique. method offers unparalleled control over synthesis doping, while also eliminating convention‐related issues. Citric acid used as source, urea, trizma base, beta‐alanine, L‐arginine, EDTA sources. Notably, urea produced NCQDs with excitation‐independent fluorescence, high yields (up 40%), uniform narrow particle size distributions. Density functional theory (DFT) time‐dependent DFT modelling established that defects substituents within graphitic have a more significant impact NCQDs’ electronic than nitrogen‐containing groups. Importantly, first time, this work demonstrates conventional approach single‐layer structures insufficient, but two layers suffice replicating experimental data. study, therefore, provides essential guidance selection NCQD customization diverse applications.

Metal-organic frameworks (MOFs) have played a pivotal role as rapid and effective luminescent sensing materials. Numerous MOFs with diverse characteristics been meticulously designed for target analytes. Previous studies highlighted the factors of spectral characteristics, energy levels, interaction forces, sensor stabilities performance in response to specific analyte. This conventional "point-to-point" approach necessitates matching materials Herein, we develop modular MOF-based platform by using mixed-ligand strategy. A MOF Eu-FDA 2,5-furandicarboxylic acid can serve foundational platform, partial replacement nine distinct hexacyclic isophthalic acids modules, respectively, specifically accommodate different analytes particular structures properties. substitution has confirmed through single-crystal X-ray diffraction.
