The mixture of Au@CdS and CdS nanoparticles were obtained by reversed micelles method. n-Dodecanethiol was used to replace dioctylsulfosuccinate sodium salt (AOT) as a protector, and the surfactant AOT was washed away by water. By adding enthanol of different quantity, the polarity of dispersed medium was regulated and the solubility of Au@CdS and CdS nanoparticles in dispersed medium was adjusted. Consequently, the Au@CdS and CdS nanoparticles were separated effectively. Ultraviolet absorption spectra, transmission electronic microscopy (TEM), energy-dispersive X-ray analysis (EDX), and fluorescence spectra were used to characterize Au@CdS nanoparticles.
