摘 要: 为了寻求新的适用于飞行器隐形的吸波材料,针对ZnO的红外光谱特性,采用燃烧法制备氧化镍(NiO)掺杂的纳米ZnO.通过XRD物相分析测试可以确定样品是由斜方(正交)六面体的NiO和六方晶体结构的ZnO组成,并有部分镍替代了锌的位置,形成了有效掺杂;通过透射电镜测试可确定样品的颗粒尺寸在30nm左右;通过红外光谱测试,可以确定样品在中远红外波段存在较宽的吸收带(6.89~16.7μm),该吸收带完全覆盖军事上雷达的中远红外波段(8-14μm)。 In order to seek a new electromagnetic wave absorbing material for aircraft stealth, aiming at IR spectrum characteristics of ZnO, the nano-material ZnO doped with NiO was prepared by a combustion method. It was determined that the sample is composed of orthorhombic hexahedron NiO and hexagonal crystal ZnO by the D/max-ra type X-ray diffractometer, the Zn position is replaced by Ni partially to form effective doping; the particle sizes of the sample are about 30 nm by the JEM 1000 EX2 transmission electron microscope ; a wide absorption band of the sample from 6.89μm to 16.7μm exists in medium-far IR band by the UV-3100 PC spectrophotometer and FTS 3000 (Bio-Rad) IR spectrometer, which covers the medium-far IR band from 8μm to 14μm of military radar.
