Synthesis of copper tin selenide (Cu 2 SnSe 3 ) nanoparticles was performed using colloidal hot-injection method under nitrogen atmosphere. Non-phosphine solvents such as oleylamine (OLAM), oleic acid (OLA), 1-octadecene (1-ODE) were employed for the synthesis of nanoparticles. Different mixture of these solvents was used to synthesis Cu 2 SnSe 3 nanoparticles at 230 °C. X-ray diffraction analysis shown that the synthesized nanoparticles under different phosphine-free solvents are possessed with cubic structure. Scanning electron microscopy, transmission electron microscopy analysis were carried out to find the size, shape of the nanoparticles synthesized through OLAM/1-ODE. The formation mechanism and coordinating effect of solvents on the structural and morphological properties of nanoparticles were discussed.
