| Influence of S/Cd Molar Ratio on the Morphology and Optical Property of CdS Microcrystalline Prepared by Microwave Hydrothermal | |
| 摘要: 采用微波水热法，以CdCl2·H2O和Na2S2O3·5H2O为镉源和硫源，在不同的S/Cd物质的量比条件下合成了CdS微晶。利用X射线衍射仪(XRD)、扫描电子显微镜(SEM)、场发射扫描电子显微镜(FE-SEM)、EDS、透射电子显微镜(TEM)等对样品的物相、形貌和元素组分进行了分析。结果表明：随着S/Cd物质的量比的增大，产物CdS的形貌发生规律性变化，由四面体结构逐渐转变为准球形结构；准球形结构具有分级结构，是由更小的纳米晶组装而成；光致发光性质研究结果表明，所得的CdS微晶具有较好的蓝光发射性能。 | |

| Abstract: CdS microcrystalline was prepared by Microwave Hydrothermal Process through the reactions of CdCl2·H2O and Na2S2O3·5H2O for different S/Cd molar ratio. The obtained product was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), field-emission scanning electron microscopy (FE-SEM), EDS, transmission electron microscopy (TEM) and photoluminescence spectroscopy(PL). The results indicate that the morphology of prepared CdS change regularly with the increase of S/Cd molar ratio, and the morphology of CdS transforms from tetrahedron to quasi-sphere; and the hierarchical quasi-spherical CdS is derived from the nanoparticles-assembly; The CdS microcrystalline can be used as a potential blue light emitting material. | |
