| 摘 要： | 采用溶胶凝胶法,在孔径为200 nm的阳极氧化铝模板中制备了Bi_3.15Nd_0.85Ti_3O_(12)纳米管阵列.通过XRD、SEM、TEM、HRTEM、SAED和Raman光谱测试手段对纳米管阵列的物相、微结构和声子振动特性进行了表征.研究表明,所合成BNdT纳米管为钙钛矿相多晶结构,纳米管外径约为200 nm,管壁厚约10 nm,管径和长度与所用AAO模板尺寸一致.Raman光谱分析表明,Nd离子取代了类钙钛矿层中A位的Bi离子.

| Abstract: | Bi3.15Nd0.85Ti3O12 (BNdT) nanotube arrays were fabricated by sol-gel method utilizing porous anodic aluminum oxide (AAO) templates with 200 nm pore diameters. The phase,microstructure and phonon vibrational properties of the BNdT nanotube arrays were characterized by XRD,SEM,TEM,HRTEM,SAED and Raman spectrum respectively. The results show that the BNdT nanotubes are polycrystalline with perovskite structure. The diameter and wall thickness of BNdT nanotubes are about 200 and 10 nm respectively,which are dep... |
