【 摘 要 】

TiO₂ nanotubes have been synthesized by solâ€�?�gel template method using alumina membrane. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman spectroscopy, UV absorption spectrum and X-ray diffraction techniques have been used to investigate the structure, morphology and optical properties of TiO₂ nanotubes. SEM image showed that TiO₂ nanotubes obtained were ordered and uniform. The diameter and length of the nanotubes were decided by the pore size and thickness of alumina template. Raman and XRD measurements confirmed the crystallinity and anatase phase of the TiO₂ nanotubes. The optical absorption measurement of TiO₂ nanotubes exhibits a blue shift with respect to that of the bulk TiO₂ owing to the quantum size effect.
