Hexagonal prismatic Cu3SnS4 nanoparticles and nanorods were synthesized by a hot-injection procedure. Changing the reaction conditions leads to the formation of different shapes. When oleylamine is used as a solvent, hexagonal prismatic particles are obtained, while a reaction in octadecene results in the formation of nanorods. The growth process of copper tin sulphide starts with the formation of djurleite copper sulphide seeds. Their reaction with Sn4+ ions leads to the formation of Cu3SnS4. These Cu3SnS4 nanocrystals form Au–Cu3SnS4 hybrid nanostructures by reaction with gold seeds.
Key words: Copper Tin Sulphide; Shape Control; Nanorods; Colloidal Synthesis; Semiconductor–Metal Hybrid Nanoparticles.
