| 摘 要： | 以四甲基二硫化秋兰姆(TMTD)为新型有机硫源,与醋酸镉在不同的反应温度、时间下合成出纳米CDS晶体,用场发射扫描电子显微镜(FE-SEM)、透射电子显微镜(TEM)、X射线粉末衍射(XRD)、傅里叶红外光谱(FT-IR)等手段研究了CDS纳米晶体的结构和形成.结果表明,反应温度、时间对CdS晶体的形貌和组成有影响,随温度升高,晶体形貌从粒子聚集体过渡到花形结构,同时讨论了纳米晶体的形成机理.

| Abstract: | CdS nanocrystals are synthesized with tetramethyl thiuram disulfide(TMTD) as new sulphur source at different reaction temperatures and time.The structure and the formation of CdS nanocrystal are investigated by field emission-scanning electron microscope(FE-SEM),transmission electron microscopy(TEM),X-ray diffraction(XRD),and Fourier transform infrared spectroscopy(FT-IR),respectively.It is found that the reaction temperature and the time influence the formation of the crystal morphology.The morphologies of... |
