Synthesis, characterization and optical spectroscopy of Eu 3+ doped titanate nanotubes

Abstract

The synthesis of Eu 3+ 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 Eu 3+-doped nanotubes exhibited strong emission lines associated with the 5D 0→ 7F J (with J from 1 to 4) transition of Eu 3+ and the differences between the luminescence properties of the precursor powders and the nanotubes were studied at low temperature.
