Study on the Pr Doped BiFeO3 Powder Prepared by Hydrothermal Process

本文采用Bi(NO3)3·5H2O和Fe(NO3)3·9H2O和Pr(NO3)3.6·H2O为原料,用水热方法制备了不同比例的Pr掺杂的BiFeO3微晶.XRD研究表明在Pr的掺杂比例达到10%时仍然能够获得纯钙钛矿结构的BiFeO3,不同比例Pr掺杂的样品均呈斜方钙钛矿相.扫描电镜研究结果表明BiFeO3粉体的尺度和彤貌通过Pr掺杂得到了调控.磁性测量结果表明:通过Pr掺杂,BiFeO3微粉的磁化曲线饱和性增强,剩余磁化强度增加.红外光谱研究表明BiFeO3具有钙钛矿结构,Pr掺杂导致了品格畸变.
