In this study, graphene/MoS2 quantum dots (G/M QDs) hybrid nanostructures were synthesized in two steps. The bulk materials were separately converted into quantum dots by combining physical exfoliation and solvothermal treatments. Then, the two QDs were assembled together in a hot water bath. The products exhibit excellent fluorescence and gas sensitivity to NO2 and NH3, which can be manipulated by adjusting the proportion of the components. The light-reinforced effect on the gas sensing properties of quantum dots was verified by analysing the photothermal heating curves. Due to these properties, the developed hybrid QDs are potentially suitable for gas sensing applications.
