Carbon dots with high quantum yields used for Fe³⁺ detection, information encryption and anti-counterfeiting

Abstract

We prepared nitrogen doped blue carbon dots (B-CDs) and applied it in detection of Fe3+ and information encryption and anti-counterfeiting.

A facile fluorescence method for the effective detection of ampicillin using antioxidant carbon dots with specific fluorescent response to ˙OH

“…1I) displayed three fitting peaks at 530.45 eV (CO), 531.39 eV (C–O), and 532.22 eV (O–CO). 36,37 By integrating structural information obtained from FTIR and XPS, it can be inferred that E-CDs are nitrogen-doped carbon dots characterized by primary surface functional groups including –COOH, –OH, and –NH 2 .…”
