Phase pure, controlled crystal structure of digenite (Cu{sub 9}S{sub 5}) copper sulfide nanoparticles were synthesized by hot injection method at the temperature of 180°C. The mixture of Oleylamine, 1-Octadecene and 1-Dodecanethiol were taken as solvent as well as capping agents. The effect of the mixture of solvents on the phase formation and morphology of the synthesized nanoparticles were analysed. The nanocrystals were characterized using X-Ray diffraction (XRD) which confirms the presence of single phase rhombohedral digenite Cu{sub 9}S{sub 5} NPs, Morphological analysis clearly depicts the formation of hexagonal faceted Cu{sub 9}S{sub 5} NPs, Energy dispersive X-ray absorption spectroscopy (EDS) reveals the stoichiometric ratio of 1.8:1 for synthesized NPs. From the UV-Vis absorption spectroscopy the bandgap value of Cu{sub 1.8}S is found to be 1.71 eV. The presence of capping agents along the surface of the Cu{sub 9}S{sub 5} NPs was confirmed from FTIR analysis.
