摘　　要：采用热蒸发方法,以红外烧结炉为制备仪器,在玻璃衬底上制备了空心的八面体纳米晶。利用扫描电子显微镜、X射线衍射谱、透射电子显微镜及选区电子衍射分析产物的形貌、尺寸、成分及结构,并对纳米晶的形成机理进行了探讨分析。Hollow octahedron nanocrystals were synthesized on glass substrate with infrared sintering furnace via thermal evaporation method. The morphology, size, composition and phase structure of octahedron nanocrystals were characterized by scanning electron microscopy（SEM）, X-ray diffraction（XRD）, transmission electron microscopy （TEM）, selected area electron diffraction（SAED） and energy dispersive spectrometer（EDS）. The octahedrons are Na2 Mo2 O7 orthorhombic structure. The formation mechanism was discussed in detail.
