【摘要】 介绍了微乳液制备硫化锌纳米粒子的过程.以硫代已酰胺(TAA)和乙酸锌(Zn(Ac)2)作为反应物,在超声波的分散作用下制备ZnS纳米粒子.采用XRD及TEM对超细样品进行表征,得到的样品为β晶型ZnS,粒子的平均粒径约为30 nm.此外,探讨反应温度对产品收率的影响以及干燥方法对粒子团聚的影响.经过比较得出结论:反应温度控制在35℃左右能得到较好的产品收率;采用真空干燥能有效地控制粒子间的团聚.更多还原

【Abstract】 The paper has introduced the microemulsion synthesis of ZnS nanoparticles.With dispersion of ultrasonic wave,ZnS nanoparticles were prepared by TAA and Zn（Ac）₂.The sample was examined by XRD and TEM,and the results showed that it was β-ZnS with the particle diameter of 30 nm.Furthermore,it was also studied that the reaction temperature affected the production rates and the drying methods influenced particles conglomeration.Through the comparisons,we concluded: when the reaction temperature was controlled in 35 ℃,better yield can be obtained;the vacuum drying could effectively control the conglomeration of particles.更多还原
