Abstract

In this paper, we present the structural, optical, electrical and magnetic properties of the copper oxide nanoparticles prepared by co-precipitation method. The prepared copper oxide nanoparticles have been characterized by scanning electron microscopy, X-ray diffraction, X-ray electron spectroscopy and Fourier transform infrared spectroscopy. CuO nanoparticles exhibit spherical shape with the average particle size of around 42 nm. The X-ray diffraction pattern reaveals the crystalline monoclinic phase. The optical properties of the CuO nanoparticles studied by diffuse reflectance spectroscopy show the blue-shifted band gap of 1.45 eV. The electrical conductivity value of the sample has been measured using Keithley meter and it is 0.16 S/m. The magnetic properties measured using vibrating sample magnetometer at room temperature show a weak ferromagnetic behaviour with the dominant paramagnetic contribution of the CuO nanoparticles. The weak room temperature ferromagnetic behaviour may be associated with the oxygen vacancies and spin ordering induced by thermal energy and reduction in particle size.

氧化铜纳米颗粒结构、光学、电学和磁性能的实验研究
本文研究了共沉淀法制备的氧化铜纳米颗粒的结构、光学、电学和磁学性能。采用扫描电子显微镜、x射线衍射、x射线电子能谱和傅里叶变换红外光谱对制备的氧化铜纳米颗粒进行了表征。CuO纳米颗粒呈球形,平均粒径约为42 nm。x射线衍射图显示晶体为单斜相。漫反射光谱研究了CuO纳米粒子的光学性质,发现其蓝移带隙为1.45 eV。用基思利电导率仪测定样品的电导率值为0.16 S/m。用振动样品磁强计在室温下测量的磁性能表明,CuO纳米颗粒具有弱铁磁性,其顺磁性占主导地位。弱的室温铁磁行为可能与热能和颗粒尺寸减小引起的氧空位和自旋有序有关。图形抽象
