摘要

本研究采用先进燃烧法制备了纳米ZnFe_2O_4。用x射线衍射和原子力显微镜对锌铁氧体表面粗糙度进行了研究。XRD测试结果表明，在400、600和800℃不同退火温度下，样品ZnFe_2O_4作为单相纳米颗粒的晶体结构呈立方状，凝胶化退火温度的增加使晶粒平均尺寸增大，在400、600和800℃时，纳米颗粒的平均尺寸分别在26.60、30.13和56.23 nm范围内。从紫外可见光谱分析可以发现，带隙和吸收光谱随吸积温度的增加而增加。

Effect of Heat Treatment on Structural and Optical Properties of ZnFe2O4 Nanoparticles

In this work, ZnFe_2O_4 nanoparticles was prepared via advanced combustion route. Zn ferrite was investigated by x-ray diffraction and the roughness of the surface describe by atomic force microscopy. From results XRD test itfs found that the crystal structureof sample ZnFe_2O_4 as a single phase nanoparticle is cubic with different annealing temperature 400, 600 and 800 .C respectively, accretion annealing temperature of the gelled to increase the crystalline average size The average size of nanoparticles in the range of 26.60, 30.13 and 56.23 nm at 400, 600 and 800 .C respectively. It can be found from UVvisible analysis the bandgap and the absorption spectrum accretion with accretion temperature.
