文摘
- •
Two kinds of graphene quantum dots were prepared using glucose and citric acid.
- •
The interaction of both GQDs with several metal ions was investigated.
- •
Au(III) ions selectively quench the fluorescence of both GQDs.
- •
Glucose-derived GQDs show better analytical performance for Au(III) determination.
