摘　　要：本文通过高温固相法制备了Eu_(0.5)Ca_(0.5)Mn_(1-x)Al_(x)O_(3)(x=0,0.1,0.2)钙钛矿稀土锰氧化物样品。对样品进行XRD测试,IR吸收光谱测试。XRD测试结果表明:样品随Al^(3+)掺杂量的增加,主峰的位置向大角度方向偏移,样品表现为单相正交结构,晶胞体积无明显改变。IR吸收光谱表明:随着Al^(3+)掺杂量增加,吸收峰大体呈现左移(短波方向)趋势,MnO6八面体J-T畸变程度减小。In this paper,Eu_(0.5)Ca_(0.5)Mn_(1-x)Al_(x)O_(3)(x=0,0.1,0.2)perovskite rare earth oxide samples were prepared by high temperature solid state method.The samples were tested by XRD and IR spectra.XRD patterns of series samples show that with the increase of Al^(3+) doping content,the position of the main peak shifts to a large angle,and the cell volume has no obvious change.The sample showed a single-phase orthogonal structure.IR absorption spectra showed that with the increase of Al^(3+) doping amount,the absorption peak generally showed a trend of left shift(shout wave direction),and the degree of J-T distortion of MnO6 octahedron decreased.
