Nanoparticles are used in a variety of areas, such as optoelectronics, medicine, and energy generation and storage. Different applications necessitate nanoparticles of different compositions and morphologies. Thus, developing fine synthetic control over phase and morphology is of interest to the field. Solution-phase nanoparticle synthesis allows control over particle shape and size, though phase purity is often an issue in ternary syntheses. Generally precursor reactivity must be balanced to avoid binary sinks; however, in the Cu-Sb-Se system, the ternaries compete with one another. Here we explore the knobs of a hot-injection synthesis in oleylamine that can be tuned to favor different Cu-Sb-Se ternary phases and different particle morphologies.
