The unique economical design of sulfur and nitrogen co-doped carbon dots with high photoluminescence quantum yield and superior performance for environmental Hg2+detection.
Nitrogen-doped carbon dots exhibit a distinct pH-sensitive/excitation-dependent photoluminescence emission feature within pH 4.0–8.0, facilitating intracellular pH sensing and multicolor imaging of live HeLa cells.
A novel 2D polysiloxane embedded with Si-doped-carbon-dots was synthesized, which shows dual-fluorescence emission, and high photoluminescence quantum yields and stability.
The first use of the combination of ammonium citrate (AC) and ethylenediamine tetraacetic acid (EDTA) as coordinating precursors for the synthesis of highly fluorescent (quantum yield = 67%) multicolour nitrogen-doped carbon dots (CDs) is reported.
