Preparation and characterization of urchine-like cadmium zinc sulfide nanostructured powder

The cadmium zinc sulfide (CdZnS) nanostructured powders with different morphologies such as nanorods, urchin like, microsphere were synthesized by co-precipitation method. In this approach, zinc nitrate (Zn(NO3)2), cadmium nitrate dihydrate (Cd(NO3)2·2H2O) and mercaptoacetic acid (MAA) were used as a Zn, Cd, and S source, respectively. The products were characterized by XRD, SEM, TEM, EDS and TG/DTG analysis. The result show that urchin like CdZnS spheres self-assembled from sword-like nanorods with diameter of 40-50 nm. Then, the optimized sample was calcined at 300 °C and morphology stability and FTIR of cadmium zinc sulfide nanostructured powder was evaluated.
