Ag3SbS4-nanocrystals were synthesized by solvothermal method in various member solvents (ethylene glycol+polyethylene glycol) and (dimethylformamide+triethenolamine). Optimum conditions for obtaining nanoparticles were determined (molar ratios of the amount of components, volume ratio of the solvent, temperature, time, etc.). The crystal structure, morphology, nano-size and chemical composition of the obtained silver thiostibiate nanostructure were studied using thermogravimetric (TG), X-ray powder diffractometer (XRD), energy dispersion spectroscopy (eds) and transmission electron microscopy (TEM). Using EDX and chemical analysis, the composition was found to correspond to the formula Ag3SbS4. The results of the TEM analysis showed that the synthesized Ag3SbS4 nanowires have diameters ranging from 150 to 200 nm, while their lengths can reach several micrometers. The dispersion solution of Ag3SbS4 nanoparticles was prepared in n-heptane, and the forbidden band width was determined from the absorption spectrum of the solution.
