摘要

采用共沉淀法制备氧化锌粉末，研究了烧结温度对氧化锌粉末的影响。采用粉末x射线衍射(PXRD)技术对其晶体结构进行了研究，并进行了物相分析。在PXRD图中可以清楚地看到ZnO粉末的纤锌矿六方晶体结构。利用Scherer公式，确定ZnO粉体的平均晶粒尺寸在27 ~ 37 nm之间。如扫描电镜(SEM)照片所示，表面生长出粒径从~100 nm到~200 nm不等的球形纳米颗粒。

Effect of sintering temperature on the structural, morphological and humidity sensing properties of ZnO nanostructure

ZnO metal oxide powder was prepared using co-precipitation method and the effect of sintering temperature was studied. Powder X-ray diffraction (PXRD) technique has been used to investigate the crystal structure and phase analysis. The wurtzite hexagonal crystal structure of the ZnO powder has been clearly seen in the PXRD pattern. Using the Scherer’s formula, the average crystallite size of ZnO powder was determined to be between 27 and 37 nm. The surface has grown spherical nanoparticles with size varying from ~100 nm to ~200 nm, as shown in the scanning electron microscopy (SEM) photograph.
