A novel method was applied to exfoliate MoS2 nanosheets synthesized by using a hydrothermal method. The MoS2 nanosheets were irradiated using an Ng:YAG laser operating at 532 nm with a 5 ns pulse duration for 15 min with different energies 40, 60, and 80 mJ. To investigate the effects of laser energy on the absorption evaluation of MoS2 nanosheets, UV-Vis spectroscopy technique was applied and energy band gaps were calculated in the range of 4.3- 4.6 eV. The successful formation of a hexagonal structure for prepared MoS2 nanosheets was confirmed by XRD analysis. A decrease in the crystallite sizes of MoS2 nanosheets from 50 to 15 nm by an increase in laser energy was a result of XRD investigations. The TEM images of the MoS2view more»
