Abstract
Many of the previously reported preparation methods for MoS2 quantum dots (QDs) are limited by production rate, time consumption, tedious processes or the final quality of the as-prepared QDs. Therefore, a simple and productive method for large-scale production of high-quality MoS2 QDs is still a challenge. We report a facile, low cost and environmentally friendly ion-intercalation assisted solvothermal route for the preparation of MoS2 QDs. In the reported method, NaOH is used as the Na+ ion source to intercalate and exfoliate the commercial MoS2 powder into nanosheets and then QDs. The reaction is carried out at a certain temperature in a Teflon-lined autoclave reactor. The UV-Vis absorption spectra of the as synthesized QDs show a peak in the near UV region (λ < 300 nm) instead of the characteristic peaks for the nanosheets. Characterization by X-ray diffraction, atomic force microscopy and photoluminescence spectroscopy also confirmed that the as-synthesized QDs had a uniform size distribution in the range of a few nanometers with mostly a monolayer structure and showed good photoluminescence (PL) properties. The proposed method has much potential for further enhancing the yield of MoS2 QDs by taking advantage of the nature of solution-based processes.
