中文摘要：

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Ф300nm，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。

英文摘要：

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 temperalure 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.
