Transition metal dichalcogenides (TMDs) is a class of emerging materials due to their attractive properties which allows them to have a cohort of applications. Ternary TMDs are underexplored and herein, for the first time we successfully synthesized layered tetragonal copper molybdenum sulfide (CMS) nanostructures using a facile, economically feasible and inexpensive colloidal hot injection method at varying reaction temperatures and times using a molybdenum diethyldithiocarbamate precursor. Morphology, structure, and optical properties of the nanostructures were analyzed by XRD, TEM, UV- VIS absorption, and PL spectroscopy. Despite changing reaction conditions, the purity and tetragonal structure of the material is maintained and monodispersed nanostructures with nanoscale lateral dimensions are obtained for all reaction temperatures and times. Collectively this study provides an avenue for the synthesis of other TMDs with a reduced reaction time, the absence of required pressure offer the opportunity to simply tailor the reaction conditions to afford materials with tunable properties for photovoltaic applications.
