Cobalt doped Zinc Oxide (Zn_1-xCo_xO) (x = 0.03) nanoparticles have been synthesized by chemical co-precipitation method at room temperature and characterized by X-ray diffraction (XRD) study. The XRD pattern indicates that Co doped ZnO NPs are with hexagonal wurtzite geometry and diffraction peaks get shifted to higher angles which is the characteristic influence of dopant Co that has an ionic radius smaller than the host cation. The true values of lattice constants have been calculated using Nelson–Riley Function. Crystallite size calculated using Scherrer formula has been compared with that estimated by uniform deformation (UDM), uniform stress deformation (USDM) and uniform deformation energy density (UDEDM) models of Williamson – Hall method, and also by size-strain plot (SSP) method. The lattice strain has also been calculated. The surface morphology and elemental analysis of the product have been characterized by field emission scanning electron microscopy (FESEM) and energy dispersive (EDAX) spectra.

钴掺杂的氧化锌（Zn _1-x Co _xO）（x = 0.03）纳米粒子已通过化学共沉淀法在室温下合成，并通过X射线衍射（XRD）研究进行了表征。XRD图谱表明Co掺杂的ZnO NP具有六方纤锌矿的几何形状，并且衍射峰移至更高的角度，这是离子半径小于主体阳离子的掺杂剂Co的特征影响。晶格常数的真实值已使用Nelson-Riley函数计算。已将使用Scherrer公式计算的微晶尺寸与通过Williamson-Hall方法的均匀变形（UDM），均匀应力变形（USDM）和均匀变形能量密度（UDEDM）模型以及尺寸应变图（SSP）估算的晶粒尺寸进行了比较方法。还已经计算出晶格应变。
