采用溶液化学法合成了硒化镉纳米粒子。用XRD和SEM对产物进行了表征。结果表明，硒化镉纳米粒子为面心立方结构，粒径分布范围为20 ~ 25 nm。讨论了硒化镉纳米粒子的生长过程。揭示了影响纳米硒化镉形貌的关键因素。结果表明，硒化镉纳米结构的尺寸分布对Cd/Se/PVP的摩尔比敏感。随着Cd/Se摩尔比的增大和Cd/PVP摩尔比的减小，CdSe纳米粒子的粒径增大。
The cadmium selenide nanoparticles were synthesized by a solution chemical route. The products were characterized by XRD and SEM. The results show that cadmium selenide nanoparticles have face-centered cubic CdSe phase which have a narrow size distribution ranging from 20 nm to 25 nm. The growth process of the cadmium selenide nanoparticles was discussed. And the key factors that influence morphology of the cadmium selenide nanoparticles were.revealed. It is indicated that the size distribution of the cadmium selenide nanostructures is sensitive to the molar proportions between Cd/Se/PVP. Specifically, the diameters of CdSe nanoparticles will increase with the increasing of the molar proportion of Cd/Se and the decreasing of the molar proportion of Cd/PVP.
