中文摘要
本项目主要研究金属氮氧化物的晶体结构、电子密度分布、电子结构和光学性质。我们采用在氨气气氛下加热金属氧化物的方法制备了钙钛矿型氮氧化物。用Rietveld和最大熵方法分析了金属氮氧化物的同步辐射X射线粉末衍射数据。
英文摘要
In this project, we have investigated the crystal structure, electron-density distribution, electronic structure and optical properties of metal oxynitrides. We prepared the perovskite-type oxynitrides by heating of metal oxides under ammonia flowing. Synchrotron X-ray powder diffraction data of metal oxynitrides were analyzed by Rietveld and maximum-entropy methods.
