In this paper, viscoelastic wormlike micelles consisting of cationic liquid-type surfactant, 1-hexadecyl-3-octyl imidazolium bromide ([CimC]Br), water and different additives were utilized for the synthesis of CdS quantum dots. First, the influence of different additives, such as [Cd(NH)]Cl and ethanethioamid (precursors for the synthesis of CdS quantum dots), and temperature on the viscoelasticity of the [CimC]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 [CimC]Br wormlike micelles is proposed.
本文利用由阳离子型液态表面活性剂 1-十六烷基-3-辛基咪唑溴化盐([CimC]Br)、水和不同添加剂组成的黏弹性蠕虫状胶束来合成 CdS 量子点。首先，通过动态和稳态流变学研究了不同添加剂（如[Cd(NH)]Cl 和乙硫酰胺（CdS 量子点合成的前体））和温度对[CimC]Br 水溶液黏弹性的影响。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[CimC]Br 蠕虫状胶束中合成 CdS 量子点的机理。
