用水热合成法得到了3个具有A位掺杂的Nd1-xCaxMnO3的样品,SEM照片显示样品具有高的纯度和结晶度,ICP分析样品的阳离子掺杂比例,x=0.8,0.7,0.6。XRD分析样品的结构,显示样品为正交晶系,Pnma空间群。
Three samples of Nd1-xCaxMnO3 with A-site doping were obtained by hydrothermal synthesis. The SEM images showed high purity and crystallinity of the samples. The cation doping ratio of ICP samples was x = 0.8, 0.7 and 0.6. XRD analysis of the sample structure shows that the sample is orthorhombic, Pnma space group.
