In this study, large-scale synthesis of Cu3SbSe4 and Cu3Sb0.98Sn0.02Se4 nanoparticles with a narrow size distribution was achieved through a rapid-injection route. These nanoparticles showed a monodisperse and quasi-spherical morphology. The Cu3SbSe4 and Cu3Sb0.98Sn0.02Se4 nanoparticle-based bulk materials were then prepared by hot-pressed sinter of the nanoparticles, and their thermoelectric performances were systematically studied. Due to the reduced lattice thermal conductivity from enhanced phonon scattering at the grain interfaces of the bulk materials, the maximum ZT value of the Cu3Sb0.98Sn0.02Se4 bulk materials reached 0.50 at 575 K
