摘要：

In this work, uniform MoS2 quantum dots (QDs) are fabricated by a novel hydrothermal-solvothermal cutting integrated route. The resulting products possess few-layer thickness with an average size about 2.6 nm. Due to the strong quantum confinement effect, the obtained MoS2 QDs showed an enlarged band gap of 3.90 eV and a good photoluminescence property. Furthermore, this cost-effective and efficacious method may provide a potential advance for preparation of other layered material QDs.
