ABSTRACT Water‐soluble fluorescent carbon quantum dots (CQDs) were synthesized via a single‐step, eco‐friendly hydrothermal process using Robinia hispida L. flowers as novel source. Advanced characterization techniques (HRTEM, XRD, XPS, FTIR, UV–vis, and fluorescence spectroscopy) revealed spherical CQDs with an average size of 3.96 ± 0.83 nm yield 5.13%. Under 365 UV light, the emitted blue fluorescence. Fluorescence quenching studies various metal ions showed significant 93.5% reduction in...
A simple and time-saving spectrofluorometric method developed using an azaflavanon-3-ol compound was used for the determination of iron in various food samples. Nitric acid hydrogen peroxide were digestion samples a closed microwave system. The validated by analyzing two certified reference materials (CRM-SA-C Sandy Soil C Mixed Polish Herbs INCT-MPH-2). Measurements carried out modified standard addition method. graph linear until 21.6 mg/L iron(III). Detection quantification limits 0.81...
Nitrogen-doped carbon nanodots (CDs) were prepared via the solvothermal method, using urea and triethylene glycol as starting materials. The as-prepared CDs had individual diameters of approximately 100 nm in clusters different sizes. surface composition optical properties characterized. They exhibited multicolor emission visible range when excited with a wide wavelength range. aqueous solution was used highly sensitive tartrazine determination. fluorescence quenching linear relationship...
In this study, Robinia hispida L leaves (RH) was used as a precursor for the first time to synthesize fluorescent carbon dots (CDs) with stable blue fluorescence by single-step hydrothermal synthesis method. Notably, innovative approach eliminates necessity toxic chemicals or hazardous substances, marking significant advancement in field. The synthesized CDs demonstrate demonstrates predominance of spherical shapes an average size 11.63 ± 1.92 nm. not only exhibit enhanced efficiency...
A simple, rapid, sensitive, and low-cost spectrofluorometric method was developed for the determination of Au(III) using 5-(2,3-dimethoxyphenyl)-3-(4-methoxyphenyl)-1-phenyl-4,5-dihydro-1H-pyrazole (L) in ethanol/water. The is based on change fluorescence intensity at 464 nm after excitation 355 as a result reaction between ligand Au(III). fluorescent emission decreased with increasing concentration. concentration, pH effect, response time, effect foreign ions were determined. From results...
A simple, environmentally friendly, inexpensive, and one-step alternative method was reported for the green biosynthesis of silver nanoparticles (AgNPs) operating Spirogyra sp. extract as a reducing stabilizing substance. Concentration AgNO3 reaction time were optimized to prepare AgNPs under controlled conditions. The synthesized characterized by UV-Vis absorption spectroscopy, fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), energy dispersive X-ray...
