用球磨法与液相沉淀法两种方法分别制备了MnO2掺杂TeO2超细粉体，并通过x射线衍射（XRD）、扫描电子显微镜（SEM）和x射线激发发射光谱（XEL）对样品的物相组成、形貌等微观结构和发光性能进行了测试表征。结果表明，通过增加球磨混合时间和改变球磨介质，用球磨法可制得3-4μm的TeO2粉体。相比球磨法，用液相沉淀法可制得更加均匀和细小的超细粉体，所得粉体的平均颗粒尺寸约为1μm，其发光强度更高。

Ball milling method and liquid-phase precipitation method were used to prepare tellurium dioxide （TeO2） powder doped with manganese dioxide （MnO2） in this article. And based on the measurement of X-ray diffraction （XRD）, scanning electron microscope （SEM） and X-ray excited luminescence （XEL）, the micro structure and luminescence properties of the samples were investigated. Results showed that the mixing time and milling medium all could affect the particle size of Mn-doped TeO2 powders. Comparing to the ball milling method, the liquid-phase precipitation method helped to synthesize smaller TeO2 （Mn） fine powders with the average 1μm size and higher luminescence intensity.
