A facile strategy of using MoS quantum dots for fluorescence-based targeted detection of nitrobenzene.

We present a simple approach for producing photoluminescent MoS quantum dots (QDs) using commercial MoS powder as a precursor along with NaOH and isopropanol. The synthesis method is particularly easy and environmentally friendly. The successful intercalation of Na ions into MoS layers and subsequent oxidative cutting reaction leads to the formation of luminescent MoS QDs.
