Easily synthesized high quantum yield sulfur- and nitrogen-doped carbon dots can serve as a very efficient fluorescent sensor for the detection of Cr(vi).
Carbon dots (CDs) with a high quantum yield of 46% are prepared using a green one-pot approach under microwaves with silkworm chrysalis which has been used for cell imaging.
A facile one step hydrothermal method to prepare nitrogen-doped carbon dots (CDs) with a high photoluminescence quantum yield using Bombyx mori silk was established, and CDs were applied as luminescent probes for selective detection of Fe3+ ions.
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.
