摘要

在这项工作中,ZnO和CeO2粉末的混合物经受铣削过程,以监测机械合金化过程。采用x射线衍射(XRD)、紫外可见吸收光谱(UV-Vis)、拉曼光谱(Raman)和光致发光光谱(photoluminescence spectroscopy)对ZnO-CeO2粉体进行了表征,研究了粉体的物相、材料的拉伸状态和粒度。晶相随磨矿时间的变化而变化,晶格参数的可能变化将有助于我们估计得到Ce掺杂ZnO的磨矿工艺效率。

Exploring Mechanical Alloying to Produce Doped ZnO
In this work, a mixture of ZnO and CeO2 powders are subjected to a milling procedure to monitor the mechanical alloying processes. ZnO-CeO2 powders have been milled during 10 to 60 hours, and have been characterized by X-ray diffraction (XRD), UV-Vis absorption, Raman and photoluminescence spectroscopies, in order to study the present phases, the tensional state of material and particle sizes. The evolution of the phases presents with the time of milling, and the possible changes in the lattice parameter will help us to estimate the efficiency of the grinding process for obtaining Ce doped ZnO.
