In this paper, viscoelastic wormlike micelles consisting of cationic liquid-type surfactant, 1-hexadecyl-3-octyl imidazolium bromide ([C₁₆imC₈]Br), water and different additives were utilized for the synthesis of CdS quantum dots. First, the influence of different additives, such as [Cd(NH₃)₆]Cl₂ and ethanethioamid (precursors for the synthesis of CdS quantum dots), and temperature on the viscoelasticity of the [C₁₆imC₈]Br aqueous solution was studied by dynamic and steady rheology. Furthermore, the synthesized CdS quantum dots and their photoluminescence properties were characterized by transmission electron microscopy (TEM), UV-Vis absorption spectroscopy, X-ray diffraction (XRD) and energy-dispersive X-ray spectroscopy (EDX). In the end, the mechanism for the synthesis of CdS quantum dots in [C₁₆imC₈]Br wormlike micelles is proposed.

由离子液体型表面活性剂[C ₁₆ imC ₈ ] Br形成的粘弹性蠕虫状胶束，用于模板辅助合成CdS量子点†

本文使用由阳离子液体型表面活性剂，1-十六烷基-3-辛基溴化咪唑鎓（[C ₁₆ imC ₈ ] Br），水和不同添加剂组成的粘弹性蠕虫状胶束来合成CdS量子点。首先，[Cd（NH ₃）₆ ] Cl ₂和乙硫酰胺（合成CdS量子点的前体）等不同添加剂和温度对[C ₁₆ imC ₈通过动态和稳定的流变学研究了] Br水溶液。此外，通过透射电子显微镜（TEM），紫外-可见吸收光谱，X射线衍射（XRD）和能量色散X射线光谱（EDX）对合成的CdS量子点及其光致发光性能进行了表征。最后，提出了在[C ₁₆ imC ₈ ] Br蠕虫状胶束中合成CdS量子点的机理。
