摘要:
通过溶胶凝胶法(Sol-gel)合成了Pr1-xCaxMnO3(x=0.4、0.45、0.5)系列纳米颗粒样品,对样品的结构和导电性质进行了研究.XRD测量结果表明样品均为单相;SEM分析显示样品粒度大小均匀,粒度大小与谢乐公式计算结果吻合;对三个系列相同颗粒大小的纳米样品导电性测量可知,随着Ca2+离子的掺杂量变小,电阻率不断变大.
Abstract:
A series of Pr1-xCaxMnO3 (x=0.4、0.45、0.5) nanoparticle samples has been synthesized through sol-gel technology, and the structure and electronic transport properties of the samples have been studied with X-ray diffraction (SEM), Scanning Electron Microscopy (SEM) and electronic transport system respectively. It has been found that all the samples are of single-phase and their sizes are well-distributed. The curves of resistivity vs. temperature have exhibited that the resistivity increases with the decreasing of Ca2+-doped quantity.
