Solid solution AgInS₂-ZnS nanostructures were prepared by reacting (Z)-1- (octadec-9-enyl)-3-phenylthiourea and 1-dodecanethiol with the corresponding metal linoleates. The combination of sulfur sources in modified ratios, which individually do not lead to significant results, resulted in the successful formation of nanorod-shaped heterostructures. The effect of sulfur source ratios on the structure, morphology, and optical properties of yellow-red emitting nanocrystals was systematically studied by X-ray diffraction (XRD), energy dispersive X-ray analysis (EDS), X-ray photoelectron spectroscopy (XPS) and scanning transmission electron microscopy (STEM) analyzes. Nanocomposite materials based on polyvinyl toluene co-divinylbenzene (PVT-DVB) were investigated for each of the resulting nanostructures. It was demonstrated that even traces of nanomaterial (∼ 0.1 wt. %) provide a high photoluminescence quantum yield (PL QY up to 61.5%) of prepared nanocomposites.

由于前体比例的改变，在纳米AgInS ₂ -ZnS固溶体异质结构中可调节的光学性能

通过使（Z）-1-（十八烷基-9-烯基）-3-苯基硫脲和1-十二烷硫醇与相应的亚油酸金属酯反应，制备固溶体AgInS ₂ -ZnS纳米结构。硫比例不同的硫源的组合（单独不会导致明显的结果）成功地形成了纳米棒状异质结构。通过X射线衍射（XRD），能量色散X射线分析（EDS），X射线光电子能谱（XPS）系统研究了硫源比例对发射黄红色纳米晶体的结构，形态和光学性能的影响。 ）和扫描透射电子显微镜（STEM）分析。基于聚乙烯甲苯共聚物的纳米复合材料对每个得到的纳米结构研究了二乙烯基苯（PVT-DVB）。事实证明，即使是痕量的纳米材料（〜0.1 wt。％）也可以提供制备的纳米复合材料的高光致发光量子产率（PL QY高达61.5％）。
