摘要

以硫化钠为硫化剂，柠檬酸钠为稳定剂，从硝酸银和硝酸锌的水胶体溶液中共同沉积获得了不同成分的硫化物 (ZnS)(Ag2S)x 异质结构。利用 XRD、HAADF-STEM、SEM、EDX 和拉曼光谱证实了 (ZnS)(Ag2S)x 异质结构的形成。在 x ≤ 0.01 的异质结构 (ZnS)(Ag2S)x 中，ZnS 和 Ag2S 纳米粒子的尺寸分别为 2-4 纳米和不超过 3 纳米。拉曼光谱显示，在（ZnS）（Ag2S）x 异质结构中加入硫化银纳米粒子会导致 Ag2S 沉积在 ZnS 纳米粒子表面。只需在 ZnS 中掺入 1 摩尔%的胶体 Ag2S 纳米粒子，就足以在 ZnS 纳米粒子表面产生硫化银外壳。

Synthesis, morphology and Raman spectroscopy of ZnS/Ag2S heteronanostructures

Sulfide (ZnS)(Ag₂S)_x heteronanostructures of various composition were obtained by co-deposition from water colloidal solutions of silver and zinc nitrates using sodium sulfide as a sulfidizer and sodium citrate as a stabilizer. The formation of (ZnS)(Ag₂S)_x heteronanostructures was confirmed using the XRD, HAADF-STEM, SEM, EDX and Raman spectroscopy. The size of ZnS and Ag₂S nanoparticles in heteronanostructures (ZnS)(Ag₂S)_x with x ≤ 0.01 is 2–4 and no more than 3 nm, respectively. Raman spectroscopy showed that addition of silver sulfide nanoparticles into (ZnS)(Ag₂S)_x heteronanostructures leads to Ag₂S deposition onto the surface of ZnS nanoparticles. Doping ZnS with only 1 mol.% of colloidal Ag₂S nanoparticles is sufficient to produce a silver sulfide shell on the surface of ZnS nanoparticles.
