From quaternary to senary high entropy antimonide nanoparticles by a facile and scalable thermal treatment method

Transition metal antimonides form a class of intermetallic compounds, which has drawn considerable attention due to their potential applications in various fields. However, the formation nanostructures containing multiple transition elements been challenge. Here, new multicomponent antimonide nanoparticles with chemical composition ranging from quaternary senary were synthesized via simple, reproducible, and scalable thermal treatment method. This method allows uniform elemental distributions single nanoparticle, demonstrating ability obtain medium- high-entropy nanostructures. The mechanism was proposed characteristics obtained investigated by X-ray diffraction, field emission scanning electron microscopy, high-resolution transmission microscopy. Under achieved optimal synthesis conditions, single-phase hexagonal structure (P63/mmc) observed for quinary samples, whereas case trace minor impurity can be observed.
