摘要 采用真空、无氧退火方法对立方晶型FeS2进行了稀土钕掺杂实验.利用X射线衍射仪和紫外可见分光光度计对样品的结构及光吸收谱进行了研究.利用Rietveld方法对掺杂样品的结构进行了精修.结果显示:由于稀土钕离子的进入,使得立方晶型FeS2晶格结构发生畸变,从而导致样品光电性能改变. FeS_2(pyrite) doped by rare earth(Nd) is prepared by annealing at high temperature in a sulfur atmosphere.The structural and photoelectrical properties of samples are studied by X-ray diffraction patterns and optical absorption spectra.The procedure used is the full profile refinement of X-ray diffraction patterns using the Rietveld method.The experimental results show the change of unit cell volume of the sample dopping of rare earth,which leads to the change of properties of the sample.
