| 摘要: 将不同的添加剂引入到低温固相反应中，快速合成了不同尺寸的ZnS纳米粒子。利用TEM表征了产物形貌，利用XRD研究了不同的添加剂、同一添加剂下不同的反应温度、不同反应时间对纳米粒子尺寸的影响。结果表明，不同的添加剂对粒子的尺寸影响较大，其中，十二烷基胺以其特殊的反应方式在较高温度下获得了较小的纳米粒子。另外，在PEG400存在条件下，反应温度和反应时间对粒子尺寸均有一定的影响。同时，对不同条件下所得产物的紫外-可见光吸收性能也进行了测试。 |

| Abstract: ZnS nanoparticles with different sizes were synthesized by low-temperature solid-state reaction in the presence of different additives. Morphology of the products was characterized by Transmission Electron Microscopy (TEM). The effects of additives, reaction temperature and heating time on the sizes of ZnS nanoparticles were investigated by XRD, and the results show that additives had important effects on the sizes of nanoparticles, and ZnS nanoparticles with small sizes were obtained at high temperature by using CH3(CH2)11NH2 as the additive, and reaction temperature and heating time affected the sizes of nanoparticles when the additive was PEG400. In addition, Optical absorption properties of the products were also studied by UV-Vis absorption spectroscopy. |
