Novel Zn/Co–N co-doped carbon quantum dot-based “on-off-on” fluorescent sensor for Fe(III) and ascorbic acid
In this work, the metal (Zn, Co) and non-metal (N) co doped carbon quantum dots (Zn/Co-NCDs) was prepared by hydrothermal method, and characterized by FT-IR, TEM and XPS. It was found that bimetal doped could effectively improve the quantum yield (QY) of carbon quantum dots. The presence of Fe(III)...
