The optical properties of 2 mixing types of CdS-CdSe nanoparticles (i.e., coprecipitated CdS-CdSe nanoparticles, CdS-coated CdSe (CdSe/CdS)) were studied. Results indicated that the co-precipitated nanoparticles kept the similar optical properties of both CdS and CdSe's, while the CdS/CdSe core-shell structure showed totally different optical properties from the simple components. We paid special attention to the core/shell structure, as the core-shell structure showed a better passivating effect. Therefore, the XRD and TEM were tested on the core-shell structure. XRD results showed that the diffraction patterns of core-shell structure were roughly the same as their simple components. And the TEM indicated the core-shell structure had a uniform dispersion in the solution. |
