Cadmium sulphide nanoparticles were grown using a wet chemical method, by dissolving the reactants, cadmium chloride and sodium sulphide in water, in the presence of mercaptoethanol (ME), which was used as a capping agent. Manganese chloride was used to dope the nanoparticles. It was found that the particle size varied with different concentrations of ME. At higher concentrations of ME, smaller sized nanoparticles were synthesized. This method also reveals the high stability of nanoparticles in water. Nanoparticle properties were investigated using UV-vis absorption, photoluminescence spectroscopy, X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. The particle sizes were measured by the XRD technique, SEM and optical absorption spectra and were in the range 2-6 nm.
硫化镉纳米粒子是通过湿化学方法生长的，将反应物氯化镉和硫化钠溶解在水中，加入巯基乙醇（ME）作为封端剂。氯化锰被用来掺杂纳米粒子。研究发现，颗粒尺寸随 ME 的浓度不同而变化。在较高浓度的 ME 存在下，合成了更小尺寸的纳米粒子。该方法还揭示了纳米粒子在水中的高稳定性。使用紫外-可见吸收、光致发光光谱、X 射线衍射（XRD）和扫描电子显微镜（SEM）技术研究了纳米粒子的性质。通过 XRD 技术、SEM 和光学吸收光谱测量了颗粒尺寸，范围为 2-6nm。
