Abstract ZnO doped with different concentrations of Al2O3 (2, 4, 6, 8 and 10 wt%) is prepared by conventional solid-state reaction method. X-ray diffraction results revealed that the samples were crystalline with a hexagonal wurtzite phase. As the concentration of alumina (Al2O3) increases in ZnO, the X-ray diffraction peaks shifts towards higher angle. This shifting in peak position and decrease in intensity reflect that Al is successfully replaced Zn in ZnO matrix. X-ray peak broadening analysis was used to evaluate the crystallite size and lattice strain by the Williamson–Hall (W–H) method and size-strain plot (SSP) method. The physical parameters such as strain, stress, and energy density values were also calculated using W–H method with different models namely uniform deformation model, uniform stress deformation model and uniform deformation energy density model. The surface morphology and elemental analysis of the prepared samples were characterized by field emission scanning electron microscopy and energy dispersive spectra.

通过威廉姆森霍尔和尺寸应变图方法对固态烧结氧化铝掺杂氧化锌陶瓷进行 X 射线峰形分析

摘要 采用常规固相反应法制备了掺杂不同浓度 Al2O3（2、4、6、8 和 10 wt%）的 ZnO。X 射线衍射结果表明样品是具有六方纤锌矿相的结晶。随着 ZnO 中氧化铝 (Al2O3) 浓度的增加，X 射线衍射峰向更高的角度移动。这种峰位置的移动和强度的降低反映了 Al 成功地取代了 ZnO 基体中的 Zn。X射线峰展宽分析用于通过威廉姆森-霍尔（W-H）方法和尺寸-应变图（SSP）方法评估微晶尺寸和晶格应变。物理参数如应变、应力和能量密度值也使用 W-H 方法计算，不同的模型即均匀变形模型，均匀应力变形模型和均匀变形能量密度模型。通过场发射扫描电子显微镜和能量色散光谱表征制备的样品的表面形貌和元素分析。
