| Abstract: | The synthesis of Eu3+ doped titania nanotubes was carried out via a hydrothermal method. X-ray diffraction and transmission electron microscope analyses showed that the nanotubes were formed by rolling multilayered titania structure with a length of up to 100 nm. The Eu3+-doped nanotubes exhibited strong emission lines associated with the 5D0→7FJ (with J from 1 to 4) transition of Eu3+ and the differences between the luminescence properties of the precursor powders and the nanotubes were studied at low temperature. |
