| 中文摘要: |
| 用简单两步法制备ZnS/PbS核壳结构复合微球,采用SEM、EDS、TEM、XRD、FT-IR和固体紫外等测试手段对核壳结构复合微球样品进行性能表征,发现所得复合微球由ZnS核和PbS壳构成,其平均粒径约为8 μm;而且具有中空结构的ZnS微球表面被很多细小的PbS颗粒包覆形成核壳结构.UV-vis表明ZnS/PbS核壳结构复合微球在紫外-可见光区都有良好的吸收,说明其在光电器件领域中将会有很好的发展前景.另外,还探讨了复合微球形成的机理. |
| 英文摘要: |
| ZnS/PbS core-shell structure composite microspheres have been prepared through a simple two-step method.The samples were characterized by SEM,EDS,TEM,XRD,FT-IR and UV-vis.The results show that ZnS core and PbS shell constituted the hollow structure ZnS/PbS composite microspheres,the average particle size is about 8μm.The results also show that the surface of the ZnS hollow microspheres have been coated by a lot of small PbS particles,which constitute the core-shell structure.UV-vis shows that the ZnS/PbS core-shell structure composite microspheres have good absorption in UV and visible light region,which indicates that the composite microspheres will have a good development in the field of photoelectric devices.In addition,preliminary study has been made for the mechanism of composite microspheres. |
