【摘要】 采用水热法制备铟锡氧化物(ITO)前驱体粉末,着重研究了温度对前驱体粉末择优取向生长形貌的影响。采用粉末X射线衍射仪(XRD)、场发射扫描电镜(FESEM)以及视频光学显微镜考察了各种温度下合成的前驱体的相结构、形貌,由此推断出其择优取向生长机理。结果表明,温度对前驱体的相结构和形貌影响非常显著,在113℃下合成的前驱体的择优取向最为明显,该温度下前驱体的生长主要沿着[100]晶向择优取向并且具有最好的空间交叉棒形貌。

【Abstract】 Indium-tin oxide(ITO) precursor powders were synthesized by hydrothermal method.The effects of temperature on the preferred orientation morphologies of the precursor powders were studied.The phase structures and morphologies were analyzed by X-ray powder diffraction(XRD),scanning electron microscopy(SEM) and video optical microscopy.Thereby their preferred orientation growth mechanisms were deduced.As the results showed,the effects of temperature on the phase structures and morphologies of the precursors were remarkable.ITO precursors synthesized at 113 ℃ had the most obvious preferred orientation and grew mainly along the direction and exhibited the best morphology of intersecting-rods.
