Strongly luminescent monolayered MoS2 prepared by effective ultrasound exfoliation
Intense ultrasound in a pressurized batch reactor was used for preparation of monolayered MoS 2 nanosheets from natural mineral molybdenite. Exfoliation of bulk MoS 2 using ultrasound is an attractive route to large-scale preparation of monolayered crystals. To evaluate the quality of delamination,...

in ethylene glycol under atmospheric pressure. The synthesised MoSQDs were characterised by photoluminescence spectroscopy and laser-scattering particle size analysis. Our easy preparation leads to very strongly green luminescing quantum dots.
