ABSTRACT Herein, highly fluorescent sulfur and nitrogen co‐doped carbon dots (N, S‐CDs) had been employed as a probe to analyze Cu 2+ in drinking water. The biogenic creatinine is known form stable complex with ; hence, it was rationally selected bioinspired substrate for the first time enhance N, S‐CDs selectivity towards . Moreover, literature surveyed guide selection of sources optimize quantum yield (QY), so thiourea disodium edetate are co‐carbonized at 270°C 40 min characterized using different techniques. resulting have homogeneous particle size distribution high QY (60.5% ± 2.09%, n = 5). produced fluorescence intensity (FI) quantitatively quenched by , achieving detection limit reached 0.07 μM. developed environmentally friendly sustainable platform, according results three widely greenness assessment tools innovative RGB 12 model, successfully detect water excellent recovery. Finally, this sensing platform rapid selective, can be determine real‐life applications.

It is of great significance to develop carbon quantum dots (CQDs) using green sources, which are cheap, non-toxic and harmless, further expand their application scopes, e.g., fluorescence sensors, blue light screening. In this study, we have prepared Peperomia tetraphylla-based (PT-CQDs) with strong water solubility, good salt resistance, specific quenching reactions excellent optical properties via a simple one-step hydrothermal method. one application, PT-CQDs utilized as sensor due high selectivity sensitivity ferric ions (Fe3+). The limit detection (LOD) was 2.7 μmol·L−1. On the other hand, PT-CQDs/polyvinyl alcohol (PVA) films ultraviolet- (UV) high-energy (HEBL)-blocking were obtained. obtained exhibited weight blocking rate 100% in UV 80% HEBL. concentrations composites could also be controlled achieve desired light-blocking rate. addition, able absorb convert it forms light. These suggest potential applications development advanced screening sensors.
