Synthesis, characterization and optical spectroscopy of Eu3+ doped titanate nanotubes

► Synthesis of Eu3+ doped titania nanotubes was carried out via a hydrothermal method. ► Structural and morphological characterization were done by XRD, Raman and TEM. ► Luminescence properties of Eu3+ ions were analyzed. ► Nanotubes were formed by rolling multilayered titania structure.
