“…As the Fe 3+ ion has a half-filled 3d orbital, it could effectively bind with the various functional groups such as −OH and −NH 2 present on the surface of NCQDs to form a coordination complex. The fluorescence quenching through the nonradiative transition process takes place by the electron transfer from the excited state (conduction band) of NCQDs to the half-filled 3d orbital of the Fe 3+ ion, a photoinduced electron transfer (PET) process. , The fluorescence decay parameters are shown in Table , and the decay curves of NCQDs in the presence and absence of Fe 3+ ions are presented in Figure a. It was found that the average lifetime of NCQDs shifted from 3.01 to 2.31 ns on the addition of Fe 3+ .…”

A facile one-step carbonization approach is reported herein for the sustainable hydrothermal synthesis of fluorescent blue nitrogen-doped carbon quantum dots (NCQDs) using banana petioles obtained as biomass waste. These NCQDs were used to design a "turnoff" fluorescent probe, which exhibited excellent sensing capability toward the selective detection of micronutrient, Fe 3+ ion, with a limit of detection (LOD) of 0.21 nM. The turnoff process involves the formation of a nonradiative charge transfer complex via a photoinduced electron transfer process. The sensor showed a linear range from 5 to 200 nM and was used for the estimation of Fe 3+ ions in real plant samples. Further, a paper-based assay was developed for the quantitative estimation of Fe 3+ with LOD values of 0.47 nM for solution-based assay and 0.94 nM for paper-based assay using a smartphone-based readout for potential on-field applications in precision agriculture. Bioimaging studies on banana leaf cells using NCQDs revealed the selective staining of stomata openings on leaf lamella. Therefore, this work provides a way for the valorization of biomass waste into functional nanomaterials without using any extra chemicals.

In this study, rose bengal‐derived carbon quantum dots (RB‐CQDs) was synthesized by a one‐step solvothermal method using rose bengal and 1,2‐phenylenediamine as precursors in ethanol at 180 °C for 10 h and purified by silica gel chromatography. The as‐synthesized RB‐CQDs disperses well in water with particle sizes ranging from 0.78 to 2.46 nm and exhibits excitation‐independent yellow fluorescent emission (529 nm), high quantum yield (44.3 %) and good biocompatibility. More importantly, the fluorescence of RB‐CQDs can be selectively quenched by Fe3+ ions with good linear correlation and the detection limit is 19.9 nM. The recoveries of this method in actual water samples are 90 % to 110 % with relative standard deviations less than 5 %.

“…1 Heavy metals can negatively impact human health, as the metals are difficult to breakdown in living organisms and can become enriched through the food chain. Among heavy metal ions, iron ions (Fe 3+ ) are vital for enzyme catalysis, oxygen transport, and cellular metabolism; 2,3 However, the incidence of certain cancers and organ dysfunction can increase when organisms consume excessive amounts of Fe 3+ . 4 In addition, ionizing radiation is commonly utilized in various industries, such as agriculture, medicine, and national defense.…”
