In this research work described synthesis of nanocomposites in the systems S–AgI and S–Ag 2 S–AgI in dimethyl sulfoxide ( DMSO , (CH 3 ) 2 SO) medium, and its some properties. Nanocomposites were obtained through the solvothermal synthesis at temperature range ( T ) 25÷160°C. The initial solutions were prepared by dissolution of sulfur ( S ), silver nitrate ( AgNO 3 ) and ammonium iodine ( NH 4 I ) in DMSO. The final products were obtained through the simple exchange reactions between initial solutions. Using the X-ray phase analysis ( XRD ), energy dispersive X-ray analysis ( EDAX ) and scanning electron microscopy ( SEM ) the samples were tested on phase and elemental composition, particle size and morphology, respectively. The results of XRD revealed that nanocomposites represented by S and AgI for system S–AgI, and by S, AgI and Ag 2 S for S–Ag 2 S–AgI system. The EDAX analysis showed the presence in composition of the investigated samples such elements like S, Ag and I for both systems. The SEM images demonstrated that both systems have a heterogeneus structure, the particles represented by flat and irregular shape. The size of the particles for S–AgI is fluctuated from 100 to 50000 nm and for S–Ag 2 S–AgI – from 90 to 4000 nm.
