Abstract: CH3CSNH2 and CdCl2 were mixed in the aqueous solution, and heated in water bath to prepare CdS nanoparticles, the size of which was about 5 nm. The factors that affect the size of CdS nanoparticles, such as the concentration of reactants, the heating time and the stablizers, were discussed.

Key words: nanoparticles, CH3CSNH2, CdCl2
