Layered MoS2, which is treated as an alternative candidate of graphene, has attracted great attention due to its large intrinsic band gap and relatively high carrier mobility. It is relatively convenient and inexpensive to prepare MoS2 through chemical synthesis route. Herein, a novel solution-based hot-injection method is used to prepare MoS2. Controlling the reaction time leads to the variation of MoS2 morphologies, which present as quantum dots and nanosheets. Detail studies are carried out to investigate the formation mechanism of MoS2. The results indicate that the formation of layered MoS2 nanosheets follows a bottom-up process, which includes three steps in the order of quantum dots, small pieces and large area nanosheets.
