Alkyl and aryl dithiocarbamates were synthesized and used to prepare ruthenium(III) dithiocarbamate complexes. The ligands and corresponding complexes were characterized by elemental analyses and spectroscopic techniques. The metal complexes were used as single source precursors to prepared HDA/oleic acid capped nanocrystals. The optical properties of the nanocrystals were studied with absorption and photoluminescence spectroscopy. The structural properties were examined using powder X-ray diffraction (PXRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). The as-prepared ruthenium sulfide nanocrystals showed narrow size distributions ranging from 2.63 to 5.78 nm. The absorption and emission spectroscopies showed that the nanocrystals have strong fluorescence with estimated particle sizes ranging from 3.68 to 7.54 nm as confirmed by the transmission electron microscopy (TEM). Scanning tunneling microscopy (STM) and scanning electron microscopy (SEM) was used to investigate the growth, structure, and morphology of the ruthenium sulfide nanoparticles. The energy dispersion spectroscopy confirm the presence of Ru and S peaks in all the samples. <br/>
