In this work, carbon nanodots (CDs) were prepared via a green and convenient microwave assisted pyrolysis of ionic liquids (ILs) and ethylenediamine. It was found that the synthesized IL-based CDs (ILCDs) exhibited a superior selective sensitivity for Cr(VI). Photoluminescence (PL) properties of the ILCDs were applied to determine the concentration of Cr(VI), which showed a wide linear range and a low detection limit. We also received promising results by using the ILCDs for Cr(VI) detection in real samples. Moreover, the synthesized ILCDs can also work as a PL nanosensors to determine temperature and pH value in solution.
