中文摘要：

通过结合溶胶-凝胶工艺和氧化铝模板制备了BaTiO3纳米点阵列。用XRD和原子力显微镜对其进行了成分和形貌分析。结果表明，通过改变基板温度，可以得到颗粒尺寸大小及分布在一定范围内变化的BaTiO3纳米点阵列，在基板温度为室温至80℃的条件下，制得的纳米点阵列颗粒尺寸为10-300nm，颗粒间距为70-900nm。与其他方法相比，此方法不需要昂贵的设备，且对基板没有特殊要求，还可以非常方便地用于其他多元氧化物纳米点阵列的制备。

英文摘要：

In this paper, the sol-gel method combined with alumina template method is proposed to prepare Ba- TiO3 nanodot arrays. The phase component and morphology of the samples are characterized by means of X-ray diffraction and atomic force microscope（AFM）. By controlling the substrate temperature, the nanodot size and distribution distance change orderly in a certain range. As the substrate temperature changes from the room temperature to 80℃, the nanodot arrays with particle size varying from 10 to 300nm and distribution distance varying from 70 to 900nm are obtained. Compared with other methods, this method doesn＇t require expensive equipment, has no special request for substrate and can be very easily used to synthesize other multicomponent oxide nanodot arrays.
