球状纳米硅氧化物的制备

以硅、二氧化硅为原料，采用水热沉积法制备了球状纳米硅氧化物。用扫描电子显微镜、透射电子显微镜、能量色散谱仪、荧光光度计等测试手段观测了样品的形貌，分析了样品的成分、结构及光致发光（PL）特性。扫描电镜、透射电镜的研究结果表明，所得样品为高纯、直径较均匀的球状纳米硅氧化物。选区电子衍射结果表明，所得纳米硅氧化物球为无定形结构。PL测试表明，样品具有较强的蓝光发射能力。

Preparation of Nanoscale Silicon Oxide Sphere Structures

Spherical nanoscale silicon oxide have been prepared by hydrothermal deposition process using silicon and silica as the starting materials. The morphology,composition,structure and PL property of the nanoscale silicon oxide were analyzed by scanning electron microscopy,transmission electron microscopy,energy dispersive X-ray spectrum and fluorescent photometer,respectively. The results show that the deposited products on the silicon substrates are spherical nanoscale silicon oxide with high pure and amorpho...
