Overview

This research demonstrates enhanced selectivity and sensitivity of carbon quantum dots for Ag⁺ ions, indicating a promising method for environmental monitoring.

Key Points

Carbon quantum dots displayed strong blue emission at 440 nm and a quantum yield of 12.61%, indicating effective synthesis.
A linear response for Ag⁺ detection was observed in the range of 10–500 µM with a detection limit of 0.103 µM.
Spectroscopic analysis revealed abundant functional groups that enhance the optical responsiveness and aqueous dispersibility of the synthesized CQDs.
Recovery tests in tap and underground water showed 96.94–100.08% with an RSD of less than 1%, demonstrating the sensor's reliability.
