摘　　要：通过物理气相沉积法在衬底上制备了有机半导体ZnTPP的一维纳米材料,利用扫描电镜(SEM)、红外光谱(IR)和粉末X射线衍射分析(PXRD)等手段对样品的形貌和结构进行了分析;并详细研究了沉积位置和源区温度等物理因素对ZnTPP纳米材料制备的影响.结果表明:ZnTPP纳米结构与原料粉末具有不同的晶体结构,因而展现出不同的光致发光行为.同时ZnTPP纳米棒的形成机制主要是基于VS机理的气态分子自组装.One-dimensional organic semiconductor ZnTPP nanostructures were successfully synthesized on the substrates by physical vapor deposition method. The morphologies and structures of the samples were analyzed by scanning electronic microscopy （SEM）, infrared spectrum （IR）, powder X-ray diffraction （PXRD） and so on. The effect of deposition position and source temperature were investigated in detail on the formation process of ZnTPP nanomaterials. The result indicates that ZnTPP nanomaterials and starting powders are two different types of polymorphism and exhibit different fluorescence emission activity. And the formation of ZnTPP nanorods may mainly attribute to the self-assembly in the gas phase on the base of VS mechanism.
