Synthesis of water-soluble fluorescent carbon dots from Setcreasea purpurea boom and its application for Br₂ detection

Abstract

Fluorescent carbon dots (CDs) were successfully synthesized via pyrolysis of Setcreasea purpurea boom, providing a simple and convenient method for the preparation of CDs without using toxic or expensive materials.

Biocompatible Carbon Quantum Dots Derived from Sugarcane Industrial Wastes for Effective Nonlinear Optical Behavior and Antimicrobial Activity Applications

“…The XRD pattern of synthesized CQDs is displayed in Figure d, which shows a broad peak position at 2θ = 21–28°. This broad peak is associated with the (0 0 2) plane and suggests the disordered pattern of carbon dots, due to the addition of N- and O-containing groups. , These observations are in good agreement with those previously reported for CQDs. − …”

Recent developments in carbon dot-based green analytical methods: new opportunities in fluorescence assays of pesticides, drugs and biomolecules

“…The synthesis procedure is generally in one stage without the requirement of more equipment. 62 Considering this, several precursors have been reported to date such as konjac flour, 63 plant leaves, 64 wool, 65 flowers 66 and Setcreasea purpurea boom 67 as carbon sources, respectively. Wei and co-workers 68 synthesized CDs via a green pyrolysis approach using gynostemma as a carbon source and then put into a porcelain boat and calcined for 4 h at 400 1C (Fig.…”

Recent advances in green carbon dots (2015–2022): synthesis, metal ion sensing, and biological applications

“…Zhai et al compared different synthetic methods to find the most suitable route to obtain fluorescent CDs from the green precursor Setcreasea purpurea boom [ 66 ]. The different methods used were hydrothermal method, and pyrolysis in a vacuum tube furnace or a muffle furnace.…”
