摘 要: 在草酸的辅助下,利用混合溶剂热法首次合成了CdS空心半球,并用XRD、SEM和TEM对产物进行了表征.实验结果表明:反应时间、反应温度对产物的形貌起到一定的调控作用.另外,初步分析了CdS空心半球的形成机理,讨论了其光学性能. In this work,novel cadmium sulfide (CdS) hollow hemispheres were successfully prepared via an oxalic acid-assisted solvothermal route the first time. The as-prepared products were characterized by X-ray powder diffraction ( XRD ), scanning electronic microscope (SEM) and transmission electron microscopy (TEM). Results show that the morphologies of the products are dependent on the reaction time and temperature. The optical properties and possible formation process for the CdS hollow hemisphere were investigated.
