【摘要】 利用化学共沉淀法,在InCl3和SnCl4混和溶液中添加PEG-1000,并滴加浓度为25%氨水,制备了ITO前驱体,在温度700℃煅烧3h后得到ITO纳米棒。利用SEM、XRD、TEM-EDS和傅立叶-红外光谱仪分别对ITO纳米棒的形貌和尺寸、结构和物相、EDS能谱和FT-IR光谱分析,并对ITO纳米棒形貌形成机理进行了探讨分析。研究结果表明,ITO纳米棒具有立方铁锰矿结构,且具有纯度高和分散性好等特点,平均直径约为Φ300nm,长度可达3000nm,长径比约达10。随着煅烧时间的延长,ITO纳米棒形貌不变,对尺寸影响不大。更多还原

【Abstract】 Indium(Ⅲ) and tin(Ⅳ) hydroxides(precursor) were synthesized via a co-precipitation process with additive of PEG-1000 in a water bath.Nanocrystalline indium tin oxide(ITO) nanorods were obtained upon calcination at temperature of 700℃ over 3h.The morphology,size,phase structure,EDS and FT-IR spectrum of ITO nanorods were characterized by transmission electron microscopy,X-ray diffraction,TEM-EDS and FT-IR spectrograph.The formation mechanism of ITO nanorods was discussed.The results show that the diameters of the as-prepeared ITO nanorods are about 300nm and the lengths reach about 3000nm,and the ratio of length to diameter reaches about 10.The as-prepared samples with cube structure are uniform,well dispersed and of high purity.ITO nanorods keep their morphology and less changes in their dimension as the time extends during calcination.更多还原
