| 摘 要： | 以氯化镉和硫代硫酸钠为原料,以乙二胺四乙酸(EDTA)为模板剂,采用微波水热(M-H)法成功制备了空心球状 CdS 纳米结构。采用 X 射线衍射仪(XRD)、场发射扫描电子显微镜(FE-SEM)、能量弥散X射线谱(EDS)和高分辨透射电子显微镜(HRTEM)对所制备的CdS 纳米结构进行表征。采用紫外-可见吸收光谱研究所制备的分等级空心球状 CdS 纳米结构的光学性能。结果表明:得到的CdS是具有纤锌矿结构的直径为 400～600nm的分等级空心球状纳米结构,这种结构由30nm左右的纳米颗粒自组装构成。EDTA和微波辐射在分等级空心球状 CdS纳米结构的形成过程中起了重要作用,讨论了这种作用并提出可能的生长机理。所制备的分等级空心球状CdS纳米结构具有较好的蓝光发射性能。

| Abstract: | Hierarchical hollow spherical CdS nanostructures were synthesized via a simple microwave hydrothermal(M-H) process using CdCl2-H2O and Na2S2O3-5H2O as raw materials and adding ethylenediaminetetraacetic acid (EDTA) as template. The obtained products were characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), energy dispersive spectroscopy (EDS), and high-resolution transmission electron microscopy (HRTEM). Ultraviolet-visible (UV-vis) spectroscopy was used to study the optical properties of CdS. The results demonstrate that the hierarchical hollow spherical CdS with a diameter range of 400-600 nm is self-assembled by nanoparticles of 30 nm and in a wurtzite structure. EDTA and microwave play an important role on the formation of the hollow hierarchical morphology. The effect of the microwave and possible growth mechanism were discussed. UV-vis spectroscopy indicates that the CdS crystallites could be used as a potential blue light emitting material. |
