- W786460388 abstract "Bi2Ti4O11在常压高温及常温高压下的拉曼散射结果表明,它的一些物理特性和相变特征与BiVO4非常相似.这意味着它也很可能成为非常有用的铁弹材料.因此进一步研究Bi2Ti4O11在掺杂情况下的物理特性是很有意义的.我们曾首次报道过Bi2-xNdxTi4O11在常温常压下的拉曼光谱,结果表明随着Nd3+离子浓度的增加,Bi2Ti4O11从单斜相转化为Nd2Ti4O11正交相过程中经过了两次相的转变.在Bi2-xSbxTi4O11体系中也观察到了类似的规律.然而这种掺杂体系发生第一次相变的机制至今并不清楚,本文将对这一问题作出深入的研究.更多还原" @default.
