摘要
采用固相反应法制备了一系列以Cu- c - o铁氧体为基的体积颗粒(Cu (1-x) Co(x)Fe2O4)，其中x在0.0 ~ 0.6之间变化。利用拉曼光谱研究了Co含量对立方镍铁氧体(CuFe2O4)结构性能的影响。与母体CuFe2O4相比，Co掺杂CuFe2O4的晶格参数略有降低。从拉曼散射光谱上看，在母晶和掺杂晶中均观察到肩状特征，表明Co、Cu和Fe离子占据了八面体位置，而四面体位置仅被Feion占据。
Effect of D-block element Co 2+ substitution on structural and vibrational properties of spinel ferrites
A series of Cu-C o ferrite based bulk particles (Cu (1-x) Co(x)Fe2O4) in which x is varied from 0.0 to 0.6 were prepared by Solid State reaction route. The influence of the Co content on the structural properties of cubic Nickel ferrites (CuFe2O4) was investigated using Raman spectroscopy. Slight reduction in the lattice parameter of Co doped CuFe2O4 has been observed as compared to the parent CuFe2O4. From Raman scattering spectra, a shoulder like feature has been observed in both parent and doped com pounds which reveals that octahedral site is occupied by Co, Cu and Fe ions and tetrahedral site is occupied by only Feion.
