Fluorescent Carbon Dots as Nanosensors for Monitoring and Imaging Fe3+ and [HPO4]2– Ions

Abstract

Nitrogen(N) and sulfur(S) codoped carbon dots (N/S-CDs) are facilely developed by a one-pot hydrothermal process from thiourea and o-phenylenediamine as carbon precursors. The as-fabricated N/S-CDs...
