Rapid synthesis of N, S co-doped carbon dots and their application for Fe3+ ion detection
Source abstract
Abstract
In this study, nitrogen and sulfur co-doped carbon dots (NSCDs) were fabricated by microwave-assisted one-pot synthesis using vitamin C and thiourea as precursors. The as-prepared NSCDs demonstrated excellent properties, including aqueous dispensability, strong fluorescence emission, excellent environmental stability, high selectivity, and sensitivity toward Fe3+ ions. The NSCD-based material can be used as a “turn off” fluorescent probe for detecting Fe3+ ions at a low detection limit (4.2 nM). In addition, the “turn off” and “turn on” of NSCD fluorescent probe could be modulated by adding Fe3+ and EDTA, indicating weak interaction between the Fe3+ ions and NSCDs.
