摘　　要：采用低温水热法，分别用溴化十六烷基三甲基铵（CTAB）和聚乙二醇（PEG-400）作为表面活性剂，合成了具有新颖结构的花瓣状和针状ZnO。采用X射线衍射仪（XRD）、扫描电镜（SEM）对花瓣状、针状以及四针状ZnO样品进行结构、形貌表征，用红外吸收光谱（IR）分析样品的红外吸收特性，通过IR-2型发射率测试仪测试样品在8～14μm波段的红外发射率。测试结果表明，花瓣状ZnO发射率最高，针状其次，四针状最低。利用粒子散射机制对形貌与发射率的关系进行了分析。Novel structures of flower-like and needle-shape ZnO were synthesized by a low temperature hydrothermal route with CTAB and PEG-400 as surfactants, respectively.The as prepared samples and tetrapod ZnO have been characterized by X-ray diffraction（XRD）,scanning electron microscope（SEM）,and infrared absorption spectrum （IR）. The infrared emissivity in 8-14μm wave band of the samples were measured by IR-2 emissivity test apparatus.The results indicate that, the flower-like ZnO emissivity is highest, needle-shape next, Tetrapod lowest.Finally, the analysis to the relation of morphology and the emissivity was proposed by the particle scattering mechanism.
