Using a novel hydrothermal synthesis, nitrogen-doped carbon dots were synthesized and shown to exhibit tunable optical and electrochemical properties.
A novel oxygen-driven method has been developed for low-cost, large-scale, and high-efficiency production of nitrogen-doped carbon dots (N-C-dots) using various alkanolamines as both precursors and solvents.
PEG-passivation enhanced the luminescence intensity of nitrogen-doped carbon dots markedly.
