Abstract: Hydrothermal treatment was successfully used to prepare pure nanocrystalline ZnS and CdS from respective amorphous sulfides. XRD indicated that both products were of cubic phase. The electron microscopy image showed that the average particle size of ZnS and CdS was about 7 nm and 5 nm respectively. The ZnS and CdS powders have narrow particle size distribution and ZnS possesses good IR transmittance in the range of 400 to 5000 cm-1.

Key words: ZnS, CdS, hydrothermal treatment
