摘要

采用灰支撑法制备了不同相的氧化钴纳米颗粒。研究了等时退火对氧化钴纳米颗粒微应变的影响。利用Williamson Hall (W-H)图分析了晶格应变对纳米粒子x射线衍射线展宽的贡献。观察到，在较高的退火温度下，微应变被释放。

Annealing effects on microstrain of cobalt oxide nanoparticles

Cobalt oxide nanoparticles in different phases have been synthesized using ash supported method. The effect of isochronal annealing on micro-strain of cobalt oxide nanoparticles has been studied. The lattice strain contribution to the x-ray diffraction line broadening in the nanoparticles was analyzed using Williamson Hall (W-H) plot. It is observed that micro-strain was released at higher annealing temperature.
