Embodiment 1
[0031] Using femtosecond laser time-domain shaping pulse sequence to regulate electronic dynamics to realize a fast and green method for preparing single-layer molybdenum disulfide quantum dots, the specific steps are as follows:
[0032] Step 1. Through the basic method of femtosecond pulse time-domain shaping, the traditional femtosecond laser pulse is modulated in the time domain into a femtosecond laser pulse sequence including two sub-pulses.
[0033] Step 2. Place the bulk molybdenum disulfide target on the bottom of the glass vessel, add 5ml of distilled water to immerse the surface of the material for about 3mm, and then focus the femtosecond laser pulse sequence modulated in step 1 on the molybdenum disulfide target and water. At the interface, the material is ablated by adjusting the energy of the femtosecond laser pulse sequence, the delay between sub-pulses, and the laser scanning speed and scanning interval.
[0034] Step 3: Put the molybdenum disulfide suspension...
