Abstract

Raman scattering enhancement has been observed from highly ordered ferroelectric Bi _3.25La _0.75Ti ₃O ₁₂ nanotube (BLT-NT) arrays prepared by a template-assisted method. Scattering enhancement factor which is the ratio of average Raman intensity per molecule for nanostructure and film is evaluated to be about 92, 257, and 623 corresponding to the outer diameters of 50, 100, and 200 nm, respectively. The phenomena can be attributed to unique surface, microstructure, grain size, and tensile stress in the curved nanotube walls. These results indicate that BLT-NT arrays are suitable for fabricating multifunctional devices due to remaining good ferroelectricity.
