Abstract 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(NO 3 ) 2 ), cadmium nitrate dihydrate (Cd(NO 3 ) 2 ·2H 2 O) 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.

类海胆硫化镉锌纳米结构粉体的制备及表征

摘要 采用共沉淀法合成了纳米棒状、海胆状、微球状等不同形貌的硫化镉锌(CdZnS)纳米结构粉体。在该方法中，硝酸锌（Zn（NO 3 ） 2 ）、二水合硝酸镉（Cd（NO 3 ） 2 ·2H 2 O）和巯基乙酸（MAA）分别用作Zn、Cd和S源。通过XRD、SEM、TEM、EDS和TG/DTG分析对产物进行表征。结果表明，海胆状 CdZnS 球体由直径为 40-50 nm 的剑状纳米棒自组装而成。然后，将优化后的样品在 300 °C 下煅烧，评估硫化镉锌纳米结构粉末的形貌稳定性和 FTIR。
