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

摘要： 直接将CH₃CSNH₂和CdCl₂水溶液混合，水浴加热，制备出了粒径为数纳米的CdS粒子，并研究了反应物浓度、加热时间及稳定剂对生成的CdS纳米粒子粒径的影响。
