In this work, molybdenum disulfide quantum dots (MoS2 QDs) were firstly prepared by hydrothermal method using sodium molybdate and glutathione as precursors, and applied in ascorbic acid detection. When joining MnO2 nanosheets into MoS2 QDs solution, they produced an obvious fluorescence quenching, which should be due to inner filter effect (IFE). Meanwhile, the fluorescent probe was formed. Interestingly,...
