在低温水热条件下,使用不同量的醋酸锌封端剂Zn(CH3 COO)2进行水热制备出不同尺寸的纳米杆晶体前驱体.XRD分析表明,合成后的晶体前驱体由非晶相组成.在300°下煅烧10小时后,纳米杆晶体前驱体结晶成具有立方萤石结构的CeO2纳米杆.采用了NANO MEASURER软件分析四个样品的平均直径分别为220,280,300和370 nm,这证实了随着醋酸锌量的增加,杆状变得越来越粗.采用三维有限元分析结果表明:随着提高CeO2纳米杆的长度,硅单晶衬底的压应力降低,纳米杆直径的影响对硅衬底压应力的影响是不规则的.

Under different conditions of low temperature hydrothermal conditions,different sizes of nano-rod crystal precursors were prepared by hydrothermal treatment using different amounts of zinc acetate capping agent Zn(CH 3COO) 2.XRD analysis indicated that the synthesized crystal precursor consisted of an amorphous phase.After calcination at 300° for 10 hours,the nanorod crystal precursor crystallized into a CeO2 nanorod having a cubic fluorite structure.The NANO MEASURER software was used to analyze the average diameter of the four samples at 220...
