In recent years, fluorescent method has become a rising star for the detection of trace amount nitroaromatic explosives. Quantum dots, as a new type of fluorescent probe material, have drawn much attention due to their facile preparation, high quantum yields and stability. In this review, the state-of-art rapid screening of nitroaromatic explosives by quantum dots based probes has been elaborated in details. The response mechanism of the photoinduced electron transfer （PET） and fluorescent resonance energy transfer （FRET） based quantum dots probes are introduced emphatieally. The characteristics of PET and FRET based quantum dots probes in explosives detection are summarized. The development trends and application of nitroaromatic explosives degradation of quantum dots probes are also prospected
