nanotube arrays(TiNT) were fabricated by electrochemical anodic oxidation method
and doped with Zn by MEWA ion implantation.The surface morphology was characterized by scanning electron microscope.Photoelectric efficiency of the doped TiNT samples under UV and visible light excitation was studied.Theoretical study of anatase TiO
2
doped with Zn was carried out by the LAPW method based on density functional theory.
