Transition metal sulfides are promising materials for a variety of applications. Especially the electronic configuration of the d-orbitals leads to unique electronic properties of transition metals and their compounds. Zinc sulfide (ZnS) is one of the most widely used transition metal sulfide due to its broad availability and relatively low toxicity as well as saturated d-orbitals. However, the synthesis approaches of ZnS nanoparticles in solution are not fully understood. We show complementary analysis with in-situ pair distribution function (PDF) and in-situ X-ray spectroscopy of the solvothermal synthesis of ZnS for a comprehensive picture of the nucleation and growth from precursors to nanoparticles.
