Electron probing, X-ray absorption near-edge structure, transmission electron microscopy and high-resolution transmission electron microscopy were used to study the diffusion, redox and growth processes of the Ag ions in the glass matrix. 利用电子探针、X射线吸收近边结构谱、透射电子显微镜和高分辨透射电子显微镜研究了银离子在玻璃中的扩散、还原和生长机理。
The source of synchrotron radiation is used to study the X-ray absorption spectroscopy of titanic nanoparticles. The techniques include X-ray Absorption Near-Edge Structure(XANES) ( XANES ) and Extended X-ray Absorption Fine Structure ( EXAFS ). 利用同步辐射光源对奈米二氧化钛材料进行X光吸收光谱研究,包括X光近缘结构(可以用来检测材料中特定原子之电子组态)及延伸X光吸收精细结构(可用来测定原子之区域结构)两大部分。
It is found that if the sol is aged longer than 20 d, it is fairly stable, and the K-pre-edge peaks of Ti in the X-ray absorption near-edge structure spectrum are similar to anatase titania. 结果表明:陈化时间超过20d的溶胶较为稳定,在X射线近边结构谱中具有与锐钛矿型TiO2相似的边前结构;
